Are the right people following you?
The vast majority of Twitter apps serve little purpose, they're kind of fun for a while or they don't really tell you anything with any value. Twitter graders, tools to measure your influence, etc, need to be taken with a pinch of salt. Today I found a tool that actually has quite a lot of value. If you are representing a brand on Twitter you need to be making sure that the right people are following you, and that's exactly what Twittersheep will help you discover. Always loving my chance to jump on to a meme, here's a tag cloud of who's following me:

Ok, very little value to myself. I was surprised by the number of "social" followers I have, but beyond that I could have predicted the rest of the words. But if you're trying to sell yourself, or your brand, online and Twitter is where your demogaphic are then its really important that the right people are following you, and this tool is a great way to keep tabs on that.
