Today sees the launch of a new Facebook application designed to make it easier for bloggers to update their blogs and microblogs from within their Facebook account.

Six Apart has created Blog It, powered by TypePad, which allows a user to update their blogs and status reports across a number of popular blogging platforms, as well as the likes of Twitter and Pownce.

Blogging via Facebook isn’t a new concept, but Six Apart claim to have launched the first service which isn’t limited to one company’s blogging services. Popular platforms such as Blogger, WordPress, Movable Type, Vox, and Twitter are all included.

Of course, Facebook gives the opportunity for greater social interaction, and Blog It allows bloggers to easily notify friends and other contacts whenever they’ve posted something new, while still having full control over which services are updated.

“Blog It is one of the few applications that takes content created inside Facebook and makes it available for use outside Facebook,” said David Recordon, Open Platforms Tech Lead at Six Apart. “Blog It users are able to update their personal blogs, business blogs, online journals, Facebook status, or Twitter or Pownce activity all from one central environment. This is a concrete step away from the silos and walled gardens of the past and toward the open web of the future.”

Blog It is obviously a work in progress (the demonstration video talks about removing the need to use HTML in a future version) but then all good tools usually are.

How useful the service will be is likely to depend on how much you rely on Facebook versus other services. Personally, I’m not yet convinced, as I use Facebook primarily for personal relationships and Twitter / LinkedIn increasingly for business relationships. While the lines are becoming increasingly blurred, I don’t want to be tied to a web interface for updating everyone — it’s why I use Twhirl for Twitter for example.

However, I’m sure for some it will be a real boon. Let us know how you get on!
