Let's talk Drupal. Coming from Wordpress, it wasn't much effort to change over. While I haven't tried importing the database yet, the interface has been a non-issue. While the home page isn't a "write a new blog post" kind of thing, there is an option only one sub-level down (right under Create Content). It's clearly a content-management system and not a pure blog: there's plenty of support for non-bloggy things, which I'm heavily considering adding.
The installation was nice and easy: just make an SQL database, navigate to
/index.php and wait while it sets up everything for me.
