20Six

20six is one of the only UK-specific blog tools around, so if you’d like your community to be British, this is the place to start blogging. The downside with this service is that you don’t get control over much more than the colours of your website unless you pay for a subscription (from £3 per month). Some features come free and are intact from the start though, including community tools and the ability to let any visitors leave comments on your work.
