Almost all the small torrents that I see pop up are already seeded relatively good (~10 seeders) though, which reinforces the fact that A. the torrents most desperately needing seeders are the older, largest ones and B. large torrents don't attract seeders because of unreasonable space requirements.

Admittedly, newer torrents seem to be split into 300gb or less pieces, which is good, but there's still a lot of monster torrents in that list.
