As an user of Windows Live Writer since December of 2008, I think Microsoft is outright torturing Windows Live Writer users. For reasons I truly don't understand, Microsoft acquired Onfolio Writer made only a few minor updates and then stopped doing anything with Windows Live Writer.
Windows Live Writer is a fantastic offline blogging tool with a WYSIWYG editor. It interfaces with just about any blog service [Blogger, LiveJournal, TypePad, WordPress, etc.] If you're a blogger you'll find this tool incredibly helpful- and it's refreshingly free from Microsoft.
When Microsoft was fighting the stupidity of having to deal with the 'live' product line, pretty much all the applications got updates and naming updates— BUT NOT Windows Live Writer.
