If you offer direct download for a large file (> .5 GB), offer a torrent.
Direct download is slow, it’s unsafe, it’s all–or–nothing. Torrents are fast, redundant, and safe.
Torrents aren’t just for sharing stolen content. Torrent is a protocol for downloading things, and it’s a damn good one. So stop acting like everyone who torrents is evil. When I buy from the Humble Indie Bundle, I get my games as torrents. When I’m downloading files and a torrent is offered, I pick the torrent.
Torrents are better than direct downloads in every way, and yet because of their association with piracy are underutilized.
Let’s end that. Let’s use torrents.
