I still don't enjoy posting my daily notes over on Baty.net's WordPress blog. I do like all the nice things that comes with doing it, though. Still noodling.
One concern I have with using Tinderbox for blogging is that export times are already becoming noticeably longer. Not long, yet, just longer. Posting several times each day is adding up quickly. I'm always tweaking, too, so any delays can quickly become annoying. Something to keep an eye on.
