Actually even writing on wordpress.com is a bit too much, sometimes I just can't help but do the text decoration (font size, bold, underline). Nowadays, I write the blogs on the evernote first, it just makes your mind of writing more fluent. (Notepad also works, but you may lose the content accidentally.) Once you got the content, move it to a blog site and put down some cosmetics are just easiest tasks to do.
