At last! Now you can use your own domain name with the excellent wordpress.com service. Actually this is pretty old news now - I almost missed this because I was on holiday and only just noticed it because Scoble has started using 'scobleizer.com' in his permalinks.
Personally I think this is huge; recently a few people have asked me for blogging service recommendations and my only reservation about wordpress.com was that you got tied into their service (because your permalinks had 'wordpress.com' in them). This move eliminates that barrer and one of the big reasons preventing potentual bloggers from starting.
Get blogging people!
