I just saw this comment by pg: http://news.ycombinator.com/item?id=1329415
I can understand pg's point of view on this. On the other hand though, I honestly wasn't aware of searchyc until I saw that thread. It seems to me that if pg won't make an official place to post links to things like that, there should be an unofficial place.
On the other hand, I can't really think of much else to put there other than a couple of iPhone apps and the link to searchyc. So is there enough content out there to justify a wiki?
