Watch What You Say in Your Blog

Related stories in both the Chronicle of Higher Education and the Capital Times caution bloggers about the dangers of sharing too much personal information.
In particular, they warn that venting petty gripes or sharing partying and dating exploits can damage your reputation, especially to a potential employer.
According to the Chronicle:

You may think your blog is a harmless outlet. You may use the faulty logic of the blogger, “Oh, no one will see it anyway.” Don’t count on it. Even if you take your blog offline while job applications are active, Google and other search engines store cached data of their prior contents. So that cranky rant might still turn up.
