Joe & Sally Want a Blogging Client Round Up

I've been slacking a bit on the Joe & Sally series of posts as of late, but today I've received a bit of help from Tim Bray, who has posted a blogging client round-up on his site, ongoing. Tim doesn't seem too enthused about any of the blogging clients out there, as he notes: "The details follow, but the conclusion is obvious: authoring for the Web pretty well sucks. These things all can be made to work, but the universe of bloggers is writing with one hand tied behind its back.
I think there's a huge opportunity lurking here: obviously it's harder than it looks or the tools wouldn't be so lame." I wonder if he has ever tried WordPress?
