"Bitzi is a website where people cooperate to identify, describe, and discover files of all types. With Bitzi:

• You can look up descriptions, comments, and ratings about your files – or contribute such info yourself
• Our precise digital fingerprints match info to exact files, so you can distinguish between similar files and search for the very best versions
• Future file-sharing tools can assure you of a file's contents before you begin downloading
• Infected or mislabeled files can be flagged, and so discovered or ignored before doing any harm.

Distributed metadata makes sense to help users avoid fake and lower-quality files. Getting a fist-fucking movie instead of the mainstream film I thought I had downloaded on eDonkey is not my idea of fun.
