For the past several weeks I've been dogfooding a cool little online/offline blog editing tool called Windows Live Writer. The Writer team just released their public Beta 1 release, so now everyone can get it. Here's the download link. 

I've tried a bunch of blog editing solutions in the past (BlogJet, Outlook, Word, you name it) and Writer is the best that I've seen so far. It nails the basics (easy setup,online/offline support, WYSIWYG editing, categories) and has some cool features that I haven't seen before (the live preview where it applies your blog's CSS to draft entries so you can see what it will look like before you post it is very cool).

Congrats to the Live Writer team on hitting their public beta milestone!
