It is a Squidoo plug in and a stand alone site that allows any Twitter user to start a discussion or ask for advice or just create a record of a thread.
“Should I buy a Blackberry or an iPhone?” or “What do you think of Guy Kawasaki’s Alltop?” or “Short reviews of The Dark Knight” or “Where should I get sushi in San Diego?” (Get more ideas for Twttrstrm uses).
Here’s the magic part: as your followers click through and respond, the storm spreads to their followers. So, in short, it’s a threaded, viral, structured conversation in the middle of the Twitter melee.
It’s free and really easy to use in tandem with your Twitter account. The unsung bonus is that you can even earn royalties from the Twttrstrm conversations you create. For you or for charity.
