Joe, I'm surprised and disappointed that no one here has any info on this.
I just clicked it to check, and you are correct, the nature of that redirect strongly suggests that they've let their Web address lapse and a cybersquatter has taken over rights to the name.
I notice that the older local menu site,
http://www.louisvillediner.com/, is still active, and I hope it might serve a similar local purpose.
I would really like to confirm Menus of Louisville's absence, though, as we have both menu sites linked from the LouisvilleHotBytes.com front page, and I don't want to leave a bad link up there for long.
Wasn't a forumite, John Lisherness, the publisher of MenusOfLouisville? John, are you lurking out there? Can you (or anyone) help clear this up?
