It looks like you can vote one time each day in each category after registering and/or signing into your Sun-Sentinel account. As the voting progresses, blogs are ranked in each category and are tracked in a “Best Overall Blog” division at the top of the page. And it appears as though the results are continuously being updated.
You know what to do.
PS: The Sun Sentinel makes you log in or set up an account. I agree it’s annoying, but hey, what price glory?
