I only really started blogging “properly” when Windows Live Writer (WLW) beta first shipped… it’s been a really user-friendly tool for blogging, for a whole load of reasons.
The WLW team has just shipped a new beta which has a nice UI polish, some great new features (like inline spell checking) and other interesting stuff like Sharepoint 2007 integration (since Sharepoint 2007 implements blogging).
Steve posted about this and other Live betas (Live Mail & Live Messenger).
