An interesting couple of days in blogging technology:

• Automattic announced the Prologue theme for WordPress.com, which seems to be an attempt to create Twitter-like functionality to their platform for workgroups
• Genial Chris Alden announced some major changes coming to Typepad, and not before time, too. (Sorry, Chris)
• Movable Type gets an Action Streams plugin which allows you to aggregate you activity around the web on your blog. Expect to see it in action here within the next few days.
