1. What I've already done was start the successful Maemo Greeters, suggesting volunteers include helpful links in their signatures. I think that's helped "build the bridge". And I know it's a small thing, but I also spend time greeting newcomers in the Welcome thread under General. I would like to think even that little bits helps.

Old-timers just need to feel they're still relevant when things change. That can be tough. But there are plenty of projects so it could be a matter of making people feel welcome enough to help.

What I need to do more often is breathe deeply before replying to antagonistic posts. Newcomers don't need to walk into a hostile environment.

2. End-users and developers need to quit worrying about titles like "end-user" and "developer". We're all technology enthusiasts or we wouldn't be in this thing. Let's focus on what we have in common and also recognize that everyone has an important part to contribute regardless of their skills, likes, etc.
