I’ve previously posted about how you can use YouTube as a crowdsourcing tool to get feedback on video concepts and creative. LinkedIn Answers is of course another great resource to pose questions for feedback or alternatively, position you or someone in your company as a thought leader and expert resource for a particular industry.

A new Twitter application called TweetBrain allows you to take advantage of crowdsourcing as well. It’s a pretty simple application. Sign in with your Twitter account info and you’ll be able to look at a stream of current questions and answers. Alternatively, you can use the search function to drill down on specific topics. Again, a great option for thought leadership positioning and also a potential way to build your sphere of Twifluence.

Be sure to check out Jack Humphrey’s post for a nice video intro to using the site.
