How would you compare a blog to a paper? I personally read just about as much papers as blog posts, with both containing valuable information and important ideas. I have my own blog, but I'm currently sitting on some ideas that could maybe... maybe be a paper. Sure, peer-review is nice, but how many people are going to read about my idea as a blog post, vs in a (pay-walled?) journal. I'm inclined to think that outside academia, a blog post may actually have a bigger reach. The paper has more bragging rights maybe though.
