If you care enough about other torrents to get a 2:1 ratio, why not about this one?
Like I said, with some DSL connections it's technically almost impossible to achieve (except you let your computer run 24/7 for some time). I'll try to reseed about half of the blockchain, I don't think I have the time and patience to reseed it entirely. I also need to delete the blockchain torrent eventually, to have more free space on my HDD for other torrents again. Such an ENORMOUS single file does bring about some problems on some set ups. ;-)
