You may have read over the past few days about a new SixApart service called Vox. (SixApart is the owner of Typepad, hoster of Petrona, and the more functional Moveable Type, used by many professional company blogs).
In a nutshell, Vox is a service that lets you keep a blog confidential to your friends and family, rather than allowing it to be viewed by the whole world. It also offers, or will offer, numerous other features, including picture tagging.
Vox will be officially launched later this year or early next, but please go to the link if this sounds as if it is just the thing you have been waiting for. The web/tech community (Tim O’Reilly, Steve Rubel et al.) have given it rave reviews, so it will be good.
