1. This will solve the 4,000+ torrents with 1 or 2 seeders.
2. This will create more activity since even if you have a slow connection and/or few leechers on that particular torrent, in time you'll get a 1:1 because of the seeding bonus.
FTN's a good site but the lack of leechers just turn me off. I only go there to check the freebies and boost my ratio. No way I'm gonna download a rls there when if I just wait 10-15mins. later, it'll show up on TL and I'll have absolutely no problems seeding it back (and the speed will be almost the same).
