It’s been up and running for a while now, but I just got an invite to join WordPress.Com. (Which is different from WordPress.Org.) It looks like the group behind WordPress is getting ready to try and eat some Typepad’s lunch.
It doesn’t have quite the full range of functions that a WordPress install does, but they’re taking feedback, so my guess is that they will be adding things until they’re finally ready to open it up.
Anyway, just thought I’d share.
