The Product Roadmap seems to be missing. Is it being redesigned, or has it been removed permanently? We would often make suggestions to specific features listed in the roadmap, and I think having certain user input into pre-release features is a better way than releasing it all at once on the public.
As I recall, a lot of users were really thrown by the update to the Comments section. We were alright, but we don't use them in any very extreme way.
