Eh, I grant your point but it's probably higher than you might think. I was an early and devoted (and thus usually broke) Compuserve user, and visited the now-preserved building back in the mid-90s. The CIS user base skewed, I would say, heavily nerd, and heavily enthusiast, and it wouldn't surprise me to learn somehow that a large percentage of the people who used the service, at least in the early days, knew where it was headquartered. Certainly would not have been true after the AOL acquisition.
