I just got some good idea from my friend, romerun. He suggested the idea to combine social network and BitTorrent together. As of now, most trackers offer a search page to find or browse the most recent torrent files. Once you look at each user detail, you will see what torrent files you are seeding or leeching. Anyway, it would be better to apply some social concept to bittorrent trackers.

Instead of browsing for new files from all users, imagine that you just browse for what your friends are downloading. No need to verify file quality because you may trust your friends. In addition, users may create new channel to add their torrent files and let other users subscribe easily. No need to search by limited, admin-defined categories.

Let me summarize the idea.

1. You are what you are.
2. You may add other users as friends or just contacts.
3. You may create new channels and you have all rights in your own channels.
4. You may allow all users or only friends to subscribe your channels.
5. You may browse for whatever happen in your network in several views, e.g., yourself, your friends, your friends of friends and all users.
6. Everything you download/upload may be added to any channels.
7. You may restrict your originated files to only your friends, only friends of friends, all users or everyone even guest.
8. This service should let you add external torrent files for recommendation to your network seamlessly. I mean something like last.fm.

Is that cool enough? For forum, just let anyone create and join groups. Umm. Actually, it is the combination of Flickr, Facebook and Multiply.
