I'll post this on the off-chance that one other person has not heard of, or already switched to
Microsoft LiveWriter, an application to make it easier to publish blog entries. I really like how easy it was to get this tool up and running. It auto detected everything for me, and it just works. I used to use w.bloggar, but it never really worked as well as I'd liked, so I ended up just using my blog engine's online posting tool via the admin interface. I still am not a hip Web 2.0 kinda guy, as I prefer to be offline and disconnected and use tools that will post when I do have connectivity. I guess that's my DataSnap briefcase days shining through.
At any rate, taking this tool through it's paces, I really like it. The fact that I can write my blog entries ahead of time and schedule them for publishing is a big bonus, too.
