Check out - Bitly.tv
Nice new site from the folks at Bit.ly to showcase popular videos based on their twitter mentions. Chances are, if you are like me, you are pummeled daily by friends and co-workers with the latest and greatest that viral video has to offer... if not, or if you just need a little instant levity, I would recommend bookmarking this page ;).
I will have to reach out and make sure Brightcove mentions are making it in here -- we have plenty of entertaining viral content, check out http://twitter.com/search#search?q=link.brightcove. We also have new support for video tweets - http://support.brightcove.com/en/docs/editing-settings-players#promo
