<p>I feel like a twitter representative :D (unfortunately I am not), I keep asking people to join twitter, and in reply they ask me ‘why?’, I tell them benefits of twitter, and then they join twitter. So finally I thought to write a blog post telling the 7 reasons to join twitter. :)</p> <h2>A great source of traffic</h2> <p><img src="http://posterous.com/getfile/files.posterous.com/temp-2011-01-06/jInrcmBEebvjIHnrtFzsiHIwsBonCEeGggayxhIupdAjIGAjFweogbfdCbes/web-traffic.jpg" alt="Increase web traffic" /></p> <p><em><a href="http://www.dtiwinegard.com/">Image credit</a></em></p> <p>Your twitter followers know that you run a blog, so whenever you write a new blog post, just post a link on twitter with the blog post title. And I am damn sure you’ll get hundreds or may be thousands of clicks only from twitter.</p> <h2>Real-time</h2> <p>Twitter is all real-time, You’ll get real-time results about anything you search on twitter. According to <a href="http://en.wikipedia.org/wiki/Twitter">Wikipedia</a>: <em>Twitter has 190 million users, generating 65 million tweets a day and handling over 800,000 search queries per day.</em> Which is around <strong>750 tweets per second</strong>. so you’ll surely get the best out of it.</p> <h2>Free of cost for your business</h2> <p>Twitter only requires a very small investment for marketing. And the investment is not money, its your time. :) Stay active on twitter, spend some time in building up your own community with twitter. set up your blog with auto-posting services, and keep sharing some great stuff with your twitter followers.</p> <h2>It’s all social</h2> <p>Twitter is a way of spreading your words worldwide. All your tweets on twitter, are not only visible to your followers, but can be viewed by <a href="http://en.wikipedia.org/wiki/Twitter">more than 175 million users</a>. And people will share them on facebook and other social networks. They will also link them to their blog.</p> <h2>Helpful for Building Valuable Relationships</h2> <blockquote><p>Laura Fitton, the author of Twitter for Dummies, chalks up success on Twitter to four basic concepts: listen, learn, care, and serve. Basically, if you listen to the community, you will learn, and if you show that you care, you are more likely to get more out of your efforts. Serving means providing something of use to the community. If you what you’re not doing that, you may be setting yourself up to fail, as Fitton talked about in <a href="http://videos.webpronews.com/2009/11/04/the-secret-to-success-on-twitter/">this interview with WebProNews</a>.</p></blockquote> <h2>The power of the Re-Tweet equals Viral Gold</h2> <blockquote><p>It’s been said that blogs can take an idea and spread it from New York to Tokyo in minutes. If that’s true, then it’s also true Twitter can do it in seconds. It takes very little time to blog something. It takes less time to email something. It takes even less time to tweet it. Send something interesting out into Twitter and folks will pick it up and repost to their own list of followers in seconds. Suddenly your own network grows infinitely. <a href="http://www.searchengineguide.com/jennifer-laycock/five-reasons-twitter-is-an-essential-soc.php">read more »</a></p></blockquote> <h2>Know what you want to</h2> <p>Twitter is not as formal as LinkedIn and making friends on Twitter is even easier than Facebook. Start following people of your domain, and stay up to date about whats happening in the world right now. Twitter is just an open place for sharing.

I will not discuss the pros and cons of Ajax, because <a href="http://en.wikipedia.org/wiki/Ajax_%28programming%29" title="Ajax programming">Wikipedia</a> already has an article about it :).</p> <p>First of all, create a Generic Handler in your website named ‘HelloWorld.ashx’ and you will see the following code by default in the handler.

It does not run in a single process on a single machine. Instead, it is typically hosted on a web server and accessed via a Web browser on a client machine. The communication between the Web server and Web browser is sent using HTTP. It is imperative you have a basic understanding of how these items work and communicate together before you start writing much code. The typical communication process between browser and server can be generalized into the following steps: </p> <p></p> <p>                1. A user uses his or her web browser to initiate a request for a web server resource. </p> <p>                2. HTTP is used to send a GET request to the web server. </p> <p>                3. The Web server processes the GET request on the server (typically locating the requested code and running it). </p> <p>                4. The Web server then sends a response back to the web browser. The HTTP protocol is used to send the HTTP response back to the Web browser. </p> <p>                5. The user’s web browser then processes the response (typically HTML and JavaScript) and renders the web page for display to the user. </p> <p>                6. The user may then enter data and perform an action such as clicking a submit button that causes his or her data to be sent back to the web server for processing. </p> <p>                7. HTTP is used to POST the data back to the Web server. </p> <p>                8. The web server then processes the POST request (again, calling your code in the process). </p> <p>                9. The Web server then sends a response back to the web browser. HTTP is used to send the HTTP response to the web browser. </p> <p>                10. The web browser again processes the response and displays the web page to the user. This process is repeated over and over during a typical web application session.</p> </p> <p><a href="http://zainshaikh.posterous.com/the-typical-communication-process-between-bro">Permalink</a> | <a href="http://zainshaikh.posterous.com/the-typical-communication-process-between-bro#comment">Leave a comment  »</a> </p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?a=aUv9WkQEyX0:XJ4GcAFdvrc:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?a=aUv9WkQEyX0:XJ4GcAFdvrc:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?d=qj6IDK7rITs" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?a=aUv9WkQEyX0:XJ4GcAFdvrc:-BTjWOF_DHI"><img src="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?i=aUv9WkQEyX0:XJ4GcAFdvrc:-BTjWOF_DHI" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?a=aUv9WkQEyX0:XJ4GcAFdvrc:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?i=aUv9WkQEyX0:XJ4GcAFdvrc:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?a=aUv9WkQEyX0:XJ4GcAFdvrc:gIN9vFwOqvQ"><img src="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?i=aUv9WkQEyX0:XJ4GcAFdvrc:gIN9vFwOqvQ" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?a=aUv9WkQEyX0:XJ4GcAFdvrc:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/ZainshaikhsPosterous?d=7Q72WNTAKBA" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/ZainshaikhsPosterous/~4/aUv9WkQEyX0" height="1" width="1"/> http://files.posterous.com/user_profile_pics/1085756/Picture_001.jpg http://posterous.com/users/5ebAZP8m6Nc5 Zain Shaikh Zain Shaikh Zain Shaikh http://zainshaikh.posterous.com/the-typical-communication-process-between-bro Mon, 04 Oct 2010 04:27:00 -0700 Google Translate API in C-Sharp http://feedproxy.google.com/~r/ZainshaikhsPosterous/~3/oQ1mjKmfOVM/google-translate-api-in-c http://zainshaikh.posterous.com/google-translate-api-in-c <p><a href="http://feedads.g.doubleclick.net/~a/AvZgrs56eRXnMLsHjIgZ38j7gt4/0/da"><img src="http://feedads.g.doubleclick.net/~a/AvZgrs56eRXnMLsHjIgZ38j7gt4/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/AvZgrs56eRXnMLsHjIgZ38j7gt4/1/da"><img src="http://feedads.g.doubleclick.net/~a/AvZgrs56eRXnMLsHjIgZ38j7gt4/1/di" border="0" ismap="true"></img></a></p><p> <p><a href="http://translate.google.com/">Google Translate</a> is such an awesome online tool to translate text from one language into other.
