A generation is about to learn the hard way about the downside of posting your entire life online. An article in the Times shows the tip of the iceberg:

Many companies that recruit on college campuses have been using search engines like Google and Yahoo to conduct background checks on seniors looking for their first job. But now, college career counselors and other experts say, some recruiters are looking up applicants on social networking sites like Facebook, MySpace, Xanga and Friendster, where college students often post risqué or teasing photographs and provocative comments about drinking, recreational drug use and sexual exploits in what some mistakenly believe is relative privacy.

Young people may be naive but they are not stupid.

The generation just hitting puberty will watch the class ahead of them get screwed out of college admissions and job offers as a result of too much online social networking.

And they won’t make the same mistake.
