Yesterday a friend pointed me at blippr.com, a new (I assume!) site that seems to merge twitter like short comments with reviews of books, music, movies and games.
As a format it works really well, you just search for whatever movie you want to see reviews for and browse through the results. Overall ratings are also aggregated to provide an overall score.
For things like movies and games I find a consensus of opinion much more useful than an in depth review followed by one persons opinion. As Blipper can also import contacts and friends from Twitter, Friendfeed and Facebook you should also be able to see what you buddies are think of the same movie, and what other things they are enjoying.
Reviews are short <160 character twitter style comments, and use a simple ‘love it’ to ‘hate it’ rating. I’m not sure if there’s a mobile interface or iPhone app but it would seem like a great addition to catch people views right as they leave the cinema (for example).
The only slight flaw I found was that if you miss spell your email address when signing in the site creates a fresh account for you… so I now have a dummy account there!
Still, I like it :)
