Confirmed, link is dead. Hopefully I still have it cached at home.
I checked Cryptic Sea's twitter (http://twitter.com/#!/crypticsea/statuses/142361681291509760
) and saw this:
Lucretiel: @crypticsea Be careful removing blog posts like that. The internet never forgets.
crypticsea: @Lucretiel It wasn't me, Anthony Weiner hacked into my account
My guess is someone from GDC contacted him about it and said something like "look, we just have too many indie devs talking about indie dev. you have no hook." and he realized he was getting all cranky over bad timing. Hope he doesn't give up on giving a talk, though.
