It's ridiculous that wikipedia is more structured and useful that most of the academic literature. I would like to start some kind of academic movement, whereby we reject closed journals, embrace the open source mentality, and collaborate on up-to-date and awesome wikis on every modern research area.

I understand that this is sort of what happens in physics - arXiv preprints (where anything good is expected to be developed into a peer-review-worthy journal article) and a specialist blogosphere. The exchange of prestige and hence the academic credit economy seems to still happen. I suspect the key factor here is arXiv being open-access. So a possible first step is to set up a preprint archive for that field and get the researchers blogging.
