I'm not quite sure yet what I plan to do with my journal. A paid account unlocks a lot of potential - redirects, email address, the ability to have it as your homepage and website with embedding... so I'm not sure where I'm going to take it. But in the end, it doesn't really matter - I've got as long as I live to decide. There's no rush. :)
I don't expect much to change because of the switch, at least not right now. But eventually. We'll see, eh?
