The Baby Boomer Facebook boom is not the only interesting fact. Add to that the significant decline (16.5%) in high schoolers, plus the 21.7% slide in collegians, and you have a puzzle worth mulling over. Are young people leaving Facebook?

Why?

Some conjecture that the “social-networking giant has morphed into a virtual parlor for the middle-aged.” After all, the 35-50s demographic represents more than a quarter of all Facebook users-a sizeable slice by anyone’s terms. Perhaps it’s because Facebook is now a place for job seekers and entrepreneurs rather than teens looking to connect.

But others dismiss the numbers with a wave of their hand. Sure the percentage figures mark a slide in “high school” and “college” attendees, but what does that say? According to one Facebook philosopher, “The data is based on which Facebook users choose to identify the school they attend on their profile pages.” With graduation just a month or so behind us, “millions of young peopledrop[ped] online affiliations with their alma maters.”

The data farm itself, istrategylabs, calls it “the most troubling statitics [sic]” and points to “rumors that these younger user groups are being aliented [sic] by their parents joining the service.”

Privacy concerns, parental fleeing, or just a graying Facebook population, the statistics do give users something to think about. Maybe you should post it on your status.

Also unfortunate is the rise of company imposters on Twitter. Companies are finding that Twitter is not just a helpful network for keeping up with friends. It’s a powerful tool for informing the market. But fraudulent accounts, created by people with a penchant for meddling, still abound. The consequences are potentially devastating. A rogue Twitter user, Tweeting under the guise of a certain company can Tweet false or embarrassing information, recommendations to purchase from a competitor, or other equally damaging information.

It’s a problem that Twitter is well aware of, and not taking lightly. After the proliferation of non-Kayne West accounts and the forthcoming profanity-laced brouhaha of the real Kayne West, Twitter proved it wants to help. Even the Tony la Russa ruckus was professionally handled by Twitter. Now, Twitter is responding to fake user requests within record time, confirming celebrity users, and bumping off users posing as companies or celebrities.

Although Twitter does not currently have a mechanism for verifying user’s legitimacy, such a program may role out this summer. Biz Stone, who helped found the social networking site, is taking the brunt of the pain for all the fake users. He wrote, “Impersonation violates Twitter’s Terms of Service and we take the issue seriously. We suspend, delete, or transfer control of accounts known to be impersonation.”

While Twitter will “be experimenting with a beta preview of what we’re calling Verified Accounts this summer” impersonators of both companies and personalities may continue. Meanwhile, you may have good reason to wonder if your favorite company starts telling you to shop at the competitor.
