@wiser, so THAT'S what that was...Thanks for the observation. Don't know enough about the bots to comment, other than the one I've seen, cheetah, that seems to be triggered if someone copy and pastes content from another website without any introducing commentary...
Yeah, I've seen Cheetah around, and from what I can tell he performs a valuable service. The other two commenters in this thread I'm pretty sure are bots, and not sure what their purpose is, other than to reward their owners handsomely if this post hits the jackpot.
