I use LJ because its really convenient for me. :3 I had a Keenspace (now ComicGenesis) account that I used for a good while though.
Instead of having the navigation strip, I do the update a couple different ways. You can access the newest page and each chapter from the main page (the profile). I'm putting entire chapters together onto one page, it may seem like a lot, but its easy since nearly every page is less than 100KBs. Its definitely different, but I'm trying to make it as convenient a set-up as possible.
Thanks for your imput~ I'll check out Wordpress sometime. ^^
