Here's an interview on Professor Salt about it:
Not sure how I feel about this, yet - it could help greatly, there are a lot of technical problems w/ the existing CH site. However, I'd also argue that a lot of the quality of the discussions and such probably are at least partly because of those same technical problems! Make it too accessible, too easy, too database-driven, and I'd bet it'll lose a lot of what makes it a worthwhile resource. Interesting problem to have. In all honesty, better search is really the only change that I think the site *needs* - every change past that runs the risk of fundamentally changing the way people use the site, which could be good or bad.
