I finally set up my own instance of wordpress at: http://www.spugbrap.com/blog
All posts/comments from the existing spugbrap.wordpress.com blog, as well as my two old Blogger blogs, have been migrated to the new site.
There are two main reasons for this change:
1. I will now be able to modify the templates/install plugins/etc., which will allow me to do some customizations I’ve been wanting to do since I first tried out wordpress.
2. Since spugbrap.com is my own domain, I can change my hosting provider anytime I want/need to, without breaking/deprecating any links, and without requiring any readers to update their bookmarks/feed settings.
