/. then Digg and then Reddit.
I got tired of reddit being too political and too liberal (although I am a liberal myself) so I was hoping/looking for something else.
Then in a StackOverflow podcast Jeff and Joe was talking about a new place where all the cool kids hung out. They didn't want to say the name in fear of it being overrun and ruined.
With a little research I found HN and haven't left since.
