Where uTorrent's search takes you to the MiniNova torrent site, BitTorrent's goes to, a pay-for-most-content site. There's an RSS tracker and search bar, just like in uTorrent, but there's where we encounter one key difference. You can pick which files in a torrent you want to download, throttle your Internet connection to suit your whims, muck about with the Web UI and, basically, do everything that uTorrent can do.
Now, in one fell swoop, BT has access to everything it lacked. Previously, BT had lacked features that other torrent innovators had spent time testing and investing in. Now, adopting its new sibling's interface has completely reinvigorated the original BitTorrent client. BitTorrent hadn't seen a major update in about two years, but that was before it bought out uTorrent. Aside from being a peer-to-peer file transfer protocol, BitTorrent is also the name of the official software used to connect to the BitTorrent network.
