Hi, BlueJay,

As usual, it's a mixed answer. When I was new, I thought for months that Joe Offer was a computer program. It seemed that, as soon as a question was asked, he was on top of it. Last fall, I met, chatted w/ him, even hugged him. He appears to be flesh & blood. He even sings!

The answer about time zones is valid, but doesn't explain the prolific individual posters. Some, like MM, work in front of a computer & follow along most of the day. I am a teacher (well, school librarian, actually). Sometimes, I post before leaving at 6 am & I'm home between 3:30 & 4 pm. In the summer months, when school is out, I'll probably be around much more. Some of the others are just out-and-out addicts! :)
