While I agree there are quite a few people using GW, which I think is good and makes GW worthwhile, LesserWrong.com currently has 30 times as much traffic as GW. So I do think that the main site interface should be the key determining factor.
I do however think that the meta point, which is the existence of an API that allows users to create third-party clients and the proof-of-concept of GW makes a large difference of whether we should move to the new codebase, since it does make a much deeper level of customization possible.
