The file-sharing organism keeps evolving and has recently shifted its course towards other ways of providing services to users, mostly thanks to the viral anti-piracy movement that has been going on for a while now.
the only problem I have with magnet links is that, you cannot initially select which files you want to download. rather, you have to wait till the magnet link gets all the torrent data, then cancel the files accordingly and some files take a while to start up. (at least in my case)
