I'm considering a move to newsgroups, but being a long time user of BitTorrent and never actually trying anything else, I'd appreciate some guidelines.
The main thing I'm having trouble understanding is where the content is found. I'm mainly interested in music, movies, tv series and video games. As such, I has found many private torrent trackers that have fulfillled my needs (What, PassThePopcorn, Broadcasthenet, BitGamer) but am yet to find the appropriate newsgroup alternatives. I've already looked at several links lurking around here, but have either found them lacking in content or presenting it in a poor way.
Are there any specific places where I should look for such content? I'm also worrying about the retention. If I'd want older content, what'd be the chances it has been reposted? Are there sites that make sure older collections are kept available instead of forgotten in the course of time?
I'd also like to take this opportunity to ask an unrelated question. What's the probability of incomplete files? I understand it depends on which provider you get, but is it a lot of hassle in general? As in, will I constantly pull my hair out because I'll be missing parts of a release?
Thanks.
