I posted this to the ESRI Ideas site:
The resource centers are static and, beyond a certain point, of little help to developers (especially the search). Provide stack overflow sites for developer communities by platform and include a wiki (like ScrewTurn or Media Wiki) to post bugs, work-arounds and best practices. Let the developers run it for the community rather than making it about marketing. It could also promote the writing of third-party developer books that newbie GIS programmers can use to get up to speed.
I got a response today that ESRI's interested in talking about it. If anybody has any suggestions or things worth bouncing off ESRI about this, comment or add an answer to this thread.
