I just grabbed this site from my Twitter stream and its EXACTLY what I need – http://bit.ly/msiIf – its a little script that compares followers of multiple accounts. Why does a business need this? Well, when you're getting started probably the best way to figure out who to follow would be the people who follow accounts that you think are interesting. For example, I can take a few of my competitors' twitter accounts, plug them in, and then see which ones of their followers are techies out there following multiple vendors and start to follow them.Very simple, very cool. Give it whirl!
