It's great that different people make contributions and post them on their website and what not for people to check out, but by the fact that it gets spread out over n-many different places, it will get lost and probably not used as much as it could be.
I do think it is cool for people to host their own stuff -- but if we could have some way of feeding everyone's contribution into one centzral place as well. Ben Hammersley's Lazyweb would be useful from a technical standpoint: just send a trackback ping from your blog post to this central repository and it gets added to the stream. Is there some other way of integrating other people's blog posts into one central blog?
Couln't we use the existing Wiki instead? Maybe do a wiki parser that'll work in the same way as the Rails-plugin system works.
