I just read this month trends at trendwatching.com, but crowdsourced trend watching is great idea. Well until new ideas stop coming. Hope you can build good user base. One thing: Ad some kind of feeds. I just wont remember the site (despite the nice design ), I don't want yet another login to remember, but might want to fallow trends and comment on a trend I am interested in. New trends, Popular trends, Random trends, etc.
