I love it when people take the best features from other sites and create something that is truly fun. This is the case of Moviestring.
com. Think of it like a mashup between IMDB and Twitter. Once you create an account, you’ll be able to create reviews for movies, with just one catch: they have to be 255 characters or shorter. This will allow anyone to read reviews and comments on their favorite movies, making the site a really fun thing to read. Another great thing is the fact that you’ll be able to see what people think about movies that are currently playing in theatres. It makes it easy for you to determine whether or not you think a movie is worth watching. There are no tediously long reviews on this site; every review is as short as a Twitter status update, so you won’t have to spend a large portion of your precious time seeing what some overpaid critic though of a movie.

Why MovieString.com It Might Be A Killer

Some Questions About MovieString.com
Wouldn’t this be better as a Facebook app? Won’t having to create another account draw people off? How about using their existing Twitter accounts?
