Just as you wouldn't, er shouldn't, drive a car without some training, it's important to know the rules of the road when you get behind the social media "wheel."

When it comes to Twitter, that means learning tw-etiquette (that's Twitter etiquette) before jumping into tweeting.

Last week Kenneth Cole inappropriately used the hashtag 'Cairo' in a tweet and attempted to take advantage of interest in news from Egypt to promote the KC spring fashion line.

As is the case with social media the backlash was immediate and very public.
