Twing is launching a new site on Tuesday where you can find out what people have written about specific topics in forums and other online communities.
The site shows search results for keywords in individual posts, topics, and whole forums and allows a lot of fine tuning for results. You can choose to include or exclude specific terms and filter so you only see items in a certain time frame, items from certain sources, or those that mention specific people or companies.
Twing searches the Web for sites and allows forum owners to submit their sites to the directory. It also shows you what topics and forums are hot, listing which are the fastest growing and most active communities.
