Why so many posts?

If you subscribe to this blog via email, you may have noticed several recent days with many posts, many of which seem recurring. I'm updating all the posts with titles, so you'll be seeing a number of older posts show up, as I go back through and update them. I'll also post, in the next few weeks, some indications of what impact this has had on Google rankings. Previously, all blog posts had just indexed under www.joshgreene.com, without the detailed URL information, and I'm now on the way to getting this changing.
