a. Ha, good question. No, I don't think I've caused anyone to start a blog. I often find myself preaching to the choir, and most of my friends who use the computers just for e-mail and writing don’t seem ready to take the plunge.
As for asking people if they have sites, sure, all the time. It's getting to the point where you almost expect people to have URLs (well, maybe not quite, but how far away can we be?).
There was a Tokyo "bloggers" party recently organised by Michael Clark and Nadine Zukoski. Apart from the MT users" gathering organised when Ben and Mena Trott were in town, this was the first time I'd attended such an event. It was great, but a little weird to meet so many web sites in the flesh.

q. By asking people if they have a weblog, I mean "do you have a weblog?" and not "do you have a website?"

a. Ah, OK. Perhaps I'm starting to think that "web site" means "weblog" when dealing with individuals. I also tend to say "site" because "weblog" is such an ugly word.

q. Yeah, I find myself thinking “blog, what an ugly word”. I would be a lot more happier if we said “weblog” for the site and just “I logged that!” instead of “I blogged that!”. The former makes much more sense in my opinion, and it’s easily much more understandable.
