Very nice. There are some other options too. You can post all of your new ones or the archives as you choose. I found that cross-posting actually put my blog below a site that I was cross-posting on for a while. Think Atheist is well tracked and placed by Google.
Morgan (the founder) has offered a Think Atheist Seed Project as well which would give you free space on the server if you are paying for server space now. Just a thought for you.
Hey David, I like where your blog is going, but we have to have the full thing up. You can keep the link on there and elude to other postings like you have on your profile page, but we don't accept the "teaser" posts. We also have a Friends of TA page that can get you a little more visibility as well.
