forum discussion for each trend
just like on any forum-type news sites people would discuss each topic/newsbit and share their opinions
What if the forum was a stream of twitter replies? Or at the least, comments were pulled from everyone who tweeted @whatthetrend #hashtag Comment on hashtag. Or @whatthetrend "Trend name" Comment on trend?
maybe usefuill if you use twitter for this (with a certain hastag)
