Tribler is a p2p file-sharing tool which uses social networking to enhance quality & performance. While I haven’t tried it yet, or even read the paper, the concept is definetly called for. Most so-so tools have a very limited perception of ’social’. It’s usualy ‘me Tarazan you world’ or ‘me Tarazan you firends’, with no intermidiate levels. In the real world, I call my mum for recipies and my dad for car advice, but wouldn’t bother sharing a video with niether (unless its a home video of their grandchildren, which I wouldn’t want to share with anyone else). Its about time systems started reflecting these basic principles of social life!
Oh, and the reason they get a ‘Web2.1′ tag is that they’re also working on tag navigation and mob ranking.
Anyway – if anyone gives them a spin, do leave a comment here!
