Random web surfing brought me to it back in November '07.
I think I was trying to find a bit torrent client. (dunno)
Anyway, graboid is a free to try directory for movies and tv shows.

( More details to anyone interested )
It's a decent service that hasn't given me any real problems. Other than being so addictive that I got a little antsy when I couldn't use my account for a few days.
I'd say that's the true measure of a program's worth. That I can't really go more than a few days without being able to download something.
