I think something we could do as a community is to make resources that help make understanding things happening here easier, like rapidly updated community guides to the available apps with screen shots showing features.
Really what we need is independent and community development of cool new things that you can't get anywhere else, a real reason to actually come here over all the other similar choices - ideally things that corporate sites would avoid because they're focusing on profit.
One tool I'm going to be working on is having an instance/community that makes it easy for people to work on collaborative design - ideally it'll be a pipeline where idea get refined into design briefs then fact finding tasks split from that and eventually it all boils up into a series of implementation tasks, testing and documentation then finally actually gets turned into an open source product or a piece of creative commons media.
