I do use BitTorrent, but it’s never going to beat the convenience of just searching for a file and getting it when p2p networks first came out.
For niche stuff like 1930s movies sometimes I need to start a few torrents to make sure at least one of them has seeds.
I have had success with soulseek for music, but what do you guys use for other types of files?
My preferred network is ed2k/kad, but for new things bittorrent and then seed to both networks through mldonkey.
