Microsoft has released a new beta version of its unexpected free blogging app, Windows Live Writer. Writer 1.0 beta puts some more polish on the program, as well as a few new features, in particular support for tagging via several services including Technorati and del.icio.us (still no Ultimate Tag Warrior), support for the new Blogger Beta, and improved category handling. It also features faster start-ups and improved style detection for blogs, and about a dozen other little improvements. On top of that, MIcrosoft has added a Writer section to Windows Live Gallery where you can download plugins for the app or submit your own. The selection is sparse just now, but it does have Firefox and IE "Blog This" plugins, an Event plugin (with hCalendar microformat support) and a Flickr plugin. Cool.
