A lot of the ideas here are good, but each of them on their own could take all the resources of your initiative and you'd still only be able to start solving one issue. The biggest meta-problem I see is the difficulty organising our thoughts and digital resources. For personal use, I use Devonthink, but it's far from ideal. For collaboration we use a hundred ways like comment threads and wiki's, which are all rather painful. But I really feel being able to organise our (collective) ideas is the key to solving all the other problems better and faster, so we should work on it first. Possibly the solution looks like a content-addressable, distributed semantic web with privacy and massive federation, on which multiple user-friendly apps can share pieces of data.
