Don’t answer “what’s your hashtag?” with “Is that like my zodiac?” Make a concerted effort to learn the lingo. Rule of thumb: don’t assume words sounding like baby talk constitute gibberish. Digg, Meebo, iFroggy and Twitter are all serious business models Wall Street is watching closely. A hashtag is a Twitter stream grouped under a specific subject—anyone can log in, comment and observe. It is also a portal to your humiliation.
Worth a read (though I would pick free iPhone over giving the bird any day…)
