I have moved my blog over to Blogengine from Wordpress. All in all, I am happy with the move. The process to get Blogengine setup was fairly simple; however, some of the necessary database privelages were not documented, but not that big of a problem. It is important to note that I am not unhappy with with wordpress. It was a good application and I will miss it. I wanted to switch over to ASP and IIS7 (I know...why?).
Blogengine does not have all the features and enhancements of the more mature Wordpress, but it has everything I require. The functionality is good, it has all of the standard features you would expect and it seems like it will be easy to customize and maintain.
