I have been upgrading a few different legal blogs lately and it is not that easy to move your blog to WordPress BUT it is worth it in the long run! I am in the process of moving this legal search marketing blog and should have it updated sometime next week. WordPress is just all around superior to Typepad, sorry Typepad you lose!
I mean WordPress is so much better in just about every single way and its much better for SEO purposes for starters and its also more flexible with its themes and plugins.
If you have a blog in typepad, RUN don't walk and get it upgraded today!
