What's with this whole blogging thing?

So, I post all the time on Yelp about local restaurants. I occasionally post on other blogs about science or academic procedures (e.g., in various PLoS sites). Is there interest in a merger of the two, and is there more generally benefit or interest in having such a blog? I'll play with this for a while and see if there's interest, cross-posting on FaceBook since there's already a group seeing what's there. Comments/ thoughts/ suggestions from bloggers or blog-watchers welcome!!! (Especially as to whether to do this such that it can be seen by the >250 students in my class next semester...)
