On Vox

I’ve been playing with Vox, the new service from SixApart. So far it seems like a really slick Ajaxy blog site with some good features (Flickr integration is especially nice), one killer feature (per-post privacy settings), and some big glaring omissions, especially the lack of compatibility with Metaweblog API tools like MarsEdit.

However, I think the lack of tools won’t keep Vox from getting users. The friends-and-family concept is killer. The blog I’ve got set up on Vox is private, so my friends and family have to join the site to view it. My question for Six Apart is, what’s the ratio of people who join to people who actually post to their blogs?
