I have recently seen a lot of discussion about usenets, and how they have good speeds, you don't have to saturate your internet connection trying to seed back, ect. ect. Unfortunately I'm a complete idiot when it comes to usenet and wikipedia is not quite as helpful as I would like. Any help would be appreciated.
How is usenet different from FTP? FTP's are highly illegal and get shut down, yet usenet seems to stay alive. I don't see any indication of any sort of peer to peer structure, so exactly to file transfers work, without allowing feds to crush it like FTP's where the host is responsible for illegal files?
I guess this kinda ties in to how downloading files actually works, but how are the speeds? I don't quite understand how this protocol works but would it be able to easily match the speeds of higher torrents sites such as SCT or SCC or other 0day sites?
I've been seeing a lot about "retention", and I'm guessing thats how long files stay alive. So does that mean that all files only last around a year? How is usenet used/how good is it for older content then? Would it be easily manageable to find tv shows/games that were released years ago?
What sort of programs do I need to be able to run it? I see things such as news downloaders, par fixers, ect. ect and was wondering how many programs/what programs you would need to use usenet efficiently. Is there a good guide on what kinds of programs to use?
And lastly I guess, do you think its worth it for the price? When BT is free? What advantages does it have over BT? What kind of features should I look for when looking for a usenet providers and whats important to keep in mind?
