Well, I finally have access to a blog on Vox… (the starter account is little more than an online profile). Seems like other people also complained:

With this release, we are also responding to your feedback that the whole starter account thing wasn’t working and have decided to shelve that feature for now. Last week, we upgraded all starter accounts to standard accounts (yay!) and have turned that account level off.

It seems pretty cool, but I don’t have any invites! So, I have no friends. If you’re on Vox, add me to your neighborhood.
