Want to know what people are thankful for this Thanksgiving? You can be sure many will be Tweeting about it. Tomorrow if you search #thanksgiving or #thankful on Twitter search, you will get a good sense of what thanks people are sharing on Twitter. Or you can go to TurkeyTwitter , a site thrown together by Joshua Premuda which gathers all Tweets with the hashtags #thanksgiving or #turkeytwitter. (I think he should add #thankful as well).
