The main reason I want to switch is that the text formatting that comes stock with wordpress is pathetically simple for 2011. This leads to the posts looking simple and do-it-yourselfer like. It creates wall text in it's default state, not to mention you can't choose your own font type or colour. It is hopeless to change anything without manually modifying the css stylesheet.
I have been looking at other self hosted blogging platforms that offer lots of the same functionality as wordpress. I just want to paste the post in, form the paragraphs and lists, insert images where I need them etc. This is essential when you're getting a new blog up and running. I want to write the posts and publish them without problems, then move on to whatever I was doing. Right now, I have mce editor installed and I have to change the font family and weight, size etc. for every single paragraph and line. This is my one and only beef with wordpress, everything else is great.
I have even investigated using joomla with a blogging plugin. I am also looking at b2evolution, moveable type etc. Are there any others that I should be aware of or use and why?
