OK, so I'm following lemmings everywhere around the world and giving Live Writer a shot. Initial impressions?
For whatever reason Live Writer wasn't able to grab my template from Blogger, so I've just got a nice generic editor instead of working in something WSYWIG-ish like my blog. The editor seems OK, but I've always been happy with BlogJet -- although keyboard shortcuts never worked in BlogJet and its creator didn't seem to be much put out by that. You can imagine my vexed state about that since it's well-known that I'm a keyboard kind of guy.
In any case, I'm looking forward to playing around with this a bit to see how it suits me. Maybe I'll be able to find out why the template thing doesn't work. I know Blogger is rather finicky about template changes. Who knows?
