A few years ago I decided to re-design migrationology.com, and I chose to use Studiopress and Genesis, which is a framework for running a wordpress based blog. I have been extremely happy with Studiopress (which is a part of Copyblogger.com). The framework is fast and reliable, and the code is clean and it’s quite easy to figure out how to use – includes lots of drag and drop features for building your blog. I’d highly recommend it for any WordPress website.
