Typepad (http://www.typepad.com) is a publishing service specifically designed for weblog users. Produced by Ben and Mena Trott, the developers of Movable Type, a popular CMS. Typepad provides 3 user packages at varying prices, the main differences in these packages are the amounts of bandwidth and hosting space available. The most expensive package, Pro, is tailored towards advanced users, the basic package for newbies.
Typepad is still in it's infancy and just opened a "Preview" release for users. Typepad looks very promising as it provides everything someone looking to publish a weblog would need, is easy to use and affordable.
