I'm running a self-hosted version of wordpress, so plugins are an option that is available. I'm wondering what the best way to have my Twitter and Facebook accounts automatically update whenever I add a new post to my blog.
I've had great luck with Twitter Tools for updating Twitter, and Networked Blogs (search on Facebook) for Facebook.
Facebook Connect WordPress Plugin (compatible with WP 3.0) is very strong. Here's a list of features from the website.
* Open Graph Social Plugins (New!), like, activity and recommendations * Build a community * Login using your Facebook account * Send comments to Facebook profile feed * Invite your friends to the blog community * See last visitors * Facebook share counter * Facebook fan page widget * Facebook comments box * Facebook user email store
Post to Twitter is a highly rated plugin to send out a tweet every time you post on your blog, and vice versa, depending on configuration.
Use http://wordpress.org/extend/plugins/twitter-tools/ for twitter than for twitter to facebook use http://restatus.me
