The advantage of a new blog is that in one you can include new information that was revealed later on in the series. Or maybe the author has a new spin on the topic that could spark fresh and new discussion. Maybe it's just me, but even when some people make new blogs about old topics, they fail to institute new points or "spins" and the blogs is equally dead. It's all about how you make the blog.

Old blogs are really only for the sake of saving space and the effort of making a new blog. I personally don't go around looking through people's two-year-old blogs in case one of them is relevant to today, so it seems a lot simpler to just make a new blog.
