Mashable (one of the top tech news aggregators and news sites on the Web), reported in August that 8% (eight percent) of companies with 1,000 or more employees had fired someone for misusing social networking sites.

How stupid can some people be? Well . . . check out this crazy post on TheNextWeb.com where the author did a Facebook screen-grab of what appears to be a real person’s update complaining about her boss, specifically:

OMG I HATE MY JOB!! My boss is a total pervvy wanker always making me do $%@* stuff just to piss me off!! WANKER!

Unfortunately for the young lady in question, it appears that her boss was one of her Friends on Facebook. DOH! And he replied. DOUBLE DOH!

The Cautionary Tale: Be careful when you update any social networking site.

In other words, think before you update Facebook, MySpace, LinkedIn or Plaxo or other social networking sites.
