Surely !

Did you visit my new HP site ? If yes, did some contents gather your interest ? Any comments welcome, especially constructive ones.

I've visited it, but haven't delved into the articles yet, apart from the "Time Voyager" story that someone linked to earlier (although I'm pretty sure I'd already read your story some time ago, and definitely wasn't confusing it with Paul Nahin's "Newton's Gift" story from Omni magazine).
