Twellow is a great example. It’s sort of like a business phone directory for Twitter. Users can be uncovered based on their field, which makes it a spectacular way to find people in your industry quickly.

One of the big challenges of getting the most out of Twitter and building a quality social network is the decision of who to follow. Twello makes it very easy to start uncovering the kind of people with whom you’d like to interact.

If you’re a little less than impressed with Twitter’s own search tools (most people feel that way), Twellow is one of those third-party options you can use to overcome the shortcoming. It’s a great way to find the people you need to find to maximize Twitter’s value to you.
