Blog It allows you to compose and post updates within the Facebook interface and have them simultaneously appear on any one of the ten supported services, including Movable Type, TypePad, Pownce, Twitter, Blogger and WordPress.
The idea behind Blog It is to simplify the process of updating all the various sites and services you use, offering a single interface for updating all your sites. It’s a bit like turning Facebook into a fire hose that sprays your thoughts across the web.
FriendFeed is also toying with similar, though much more limited cross-posting features, like the ability to send comments to Twitter. Blog It, however, offers far more complete updating capabilities.
Which isn’t to say that Blog It is feature complete just yet. For now, you’ll miss niceties like a rich text editor or the ability to upload and include pictures in your posts. In the video below, Six Apart’s David Recordon makes it clear that the company is aware of the application's short-comings and promises feature upgrades in the near future.
But while Blog It may be a work in progress, even in limited form, it’s the easiest way I’ve seen to broadcast posts across platforms. It offers the ability to pick and choose which posts go where on a per-post basis so you’re always in control of who sees what. Every time you add a new service to update, Blog It offers the option to automatically post to that service, though you can always uncheck any of the services when you actually post something.
Blog It is a pretty slick Facebook app, perhaps the best I’ve used. And while it still lacks a few features (OAuth support is reportedly in the works, but for now you’ll have to give Blog It all of your passwords) it definitely makes it easier to broadcast your life to multiple locations. It's a nice cure for the fatigue of having to keep up with all of your data streams by logging into each service separately.
Recordan has hinted elsewhere that Six Apart may expand Blog It to work from other platforms — like Plaxo’s Pulse, or perhaps even as standalone AIR application like Twhirl — but for now Blog It is tied to Facebook.
To get an idea of what Blog It looks like in action, check out the video below where Recordon walks you through the process of setting up and using Blog It (and also offers the best OAuth metaphor I’ve heard: “it’s like a valet key for the web”). If you’d like to jump in with both feet, you can go ahead and add Blog It to your Facebook account.
