A while ago I messed around with the idea of a Twitter bot that, using hashtags, would rebroadcast anything that someone thought that others should know about (e.g. "check out this band they are great"). The idea wasn't that these recommendations were directed at anyone in particular, but instead played upon the human nature of people wanting to tell other people about something they think is great (see latest buzz on Susan Boyle video from Britain's Got Talent).
I only took that original project so far, but today I revisited it briefly and made some tweaks (influenced by the existing Twitter bot @new_music).
Basically, it looks at Metacritic's movie feed, scrapes the scores off the pages (since they aren't in the feed itself) and filters the results to only display the stuff that has an aggregate metascore of 65 or greater. When it finds one of those, it then hits YouTube to pull the trailer for the video. From there it shortens the URL and then tweets the results out at @uncovery.
I may also start to splice in music, DVDs and other content too... but will let this run a while to see how it feels. As always, comments and thoughts welcome.
UPDATE: I also have spliced in Rotten Tomatoes feed too.
