Many of us are at Wikimania right now. Today through Saturday, a few sessions you might be interested in:

Later today, Movement broadcasting mechanisms: https://wikimania2012.wikimedia.org/wiki/Submissions/Movement_Broadcasting_-...

Saturday, "Transparency and collaboration in Wikimedia engineering" https://wikimania2012.wikimedia.org/wiki/Submissions/Transparency_and_collab...

Also Saturday, "What Does THAT mean? Engineering Jargon And Procedures Explained": https://wikimania2012.wikimedia.org/wiki/Submissions/What_Does_THAT_mean%3F_...

If you can only come to one of those, "transparency and collaboration" would probably be the best one to hit to talk specifically about wikitech-ambassadors issues. Looking forward to talking with you!
