i find the fisheye access very helpful, especially for determining what's under active development and what's not. i think fisheye will allow me to refine my forum searches. but i'm always looking for authoritative summaries indicating current state of the code. fisheye seems to omit that meta-metadata unless i've overlooked it. the terrific new wiki may fill that need.
