You have hit the problem on the head. I'm very interested in surfacing better information for potential new contributors, and these are all points that I've harped on before. There's an eternal tradeoff - things like wiki pages are easy to slap together, but just as easily can grow stale. Information that is retrieved from live databases is almost always better, but such dashboards can be complicated beasts to both build and make useful, especially with projects like Mozilla that are distributed among many different silos. Getting other people to care about keeping information relevant is another problem I face. So yeah, no solutions, just acknowledgement that you're right.
