TweetBrain is a crowdsourcing web application for the Twitter community.

Features:

• sign in using Twitter credentials
• post questions with optional reward, deadline and topic category
• ability to mark questions as favorite
• RSS feed for all questions posted
• “hotlist” feature showing top topics, questions and rewards as well as top questioners and “answerers”
• user configurable settings for auto-following and visibility
• search feature

The Good:

TweetBrain is a great crowdsourcing tool for Twitter. You could post your questions directly to Twitter, but with TweetBrain your question will almost certainly be looked at by more people than already follow you (unless you are @cnn). The tool is easy to use and generates some interesting feedback. Every question you ask is posted as a tweet. It is also possible that TweetBrain could help you get more followers, given its “viral” potential.

The Not-so-Good:

So far, we like TweetBrain quite a bit. Some may have concerns about the sign-in procedure with full Twitter credentials, but that issue is addressed in the FAQ: OAuth will be used when it is ready. We’re not too sure about the reward feature. TweetBrain uses PayPal to facilitate payment of the (often nominal) reward that any user can assign to their question. That feature may not appeal to some users, but the good news is that it isn’t mandatory.
