I recently discovered that you don't need a big public HTTP tracker like The Pirate Bay to share a torrent. You can just add a UDP tracker like the one at opentrackr.org and share the magnet link.

It seems like this would be a better solution than the usual "I'll upload this to a filehost so you can download it" business. It's faster, no threat of DMCA takedown, no risk of an upload failing and having to start over, you can pause a download and resume it later if you need to... I wonder why plain ol' bittorrent isn't used more for this kind of personal filesharing. Like who needs peertube? People can just say "I have a new video, here's the magnet link, check it out." You can even configure the client to download the parts sequentially so you can watch as it downloads

True, most people don't have the upstream to support more than one or two people doing this at the same time, but for small networks of people sharing videos with their friends maybe that's enough
