It was HN, for me.
At first, I went to digg for the wonderful tech/startup stories that would surface - then it evolved into meaningless crap.
I languished for a little, with no where to go, then found HN. People complain about how HN is getting so bad, but it's nothing as bad as when Digg started to get diluted by mainstream interests.
The truth is that Digg definitely had to cater to a broader audience to sustain growth, and I have always been a Rose fan, but it's kinda sad to see it go by the wayside like this.
At least Kevin tried something with v4, but it was too little too late.
