Blog carnivals and competitions

I thought of a couple of other approaches for finding great science blogs:

1. Blog carnivals are collections of blog posts on specific topics.  Authors can submit their own posts, which are then hosted by a different blog on a rotating basis.  For example, Carnival of the Blue is a marine themed carnival.
2. Best of competitions - these are judged events to select the best blog posts.  The Open Laboratory is one of the better known examples from science.  If you write something great this semester think about submitting it for the 2009 competition later this year.
