blogs and wikis, oh my!

A blog is like an online diary that an individual creates, but that allows others to post their comments to. But those comments don't get incorporated into the 'meat' of the blog - rather they are more like asides. A wiki is a truly collaborative venture, where an individual can post content, but then anyone is able to edit and change that content. (Depending on how open the wiki is.) Wikis would be great for collaboration of a research project across mulitple institutions. I am working on a research project with a PI who is collaborating with several other institutions in various geographically dispersed areas. The PI was excited about using a personal file management program and sharing references, but now I'm thinking we could take it a step further and collaborate on the actual article and research findings on a members only wiki. I'm not seeing as much use for a blog. Initially, I thought it might be useful - we have one at our library to let people know what's new and different and to try and start dialog amongst our users on topics like personal file management software or the NIH public access policy. But no one is looking at it. I think it's just one more thing to look at and people are overwhelmed.
