I love the idea of helping build these community databases and make those contents searchable. I see a challange in the fact that this means adding another channel to discuss contents different than the one they already use, but the promise of making those contents easier to reach might make it worth it.
As for the blog problem, I'm in a similar situation. A blog seems to have some lifespan, and there are some raw contents that I would like to have available without worring about a domain name and the design decisions of CMS theme. I have my own particular "delicious", some comments about different articles, a bunch of photos, and many screenshots and mockups from the different projects I've been working on that I would like just to publish without fuzz (Ideally: add all my project folders. Done). It won't be as beautiful as those web portfolios but I don't need that, I want convenience, I don't like abondend blogs either and I have 3 or 4...
Reading these comments gets me really motivated, thanks!
