As a Gnome Desktop user I try to avoid using KDE apps, and one of the apps I scraped recently is KTorrent in favour of Transmission.
Transmission is a non-intrusive torrent client which works the Gnome way : Downloading and sharing torrents without bells and whistles.
As an Ubuntu Feisty user I downloaded the latest stable transmission with Firefox from getdeb.net and let GDebi install it.
