Why don't I use Black Ink's Open Web Puzzle feature? For a while I thought it was just habit. Then I tried it a bit and realized that I really depend on the visual organization of the Puzzle Pointers page and on the browser conveniently changing the color of visited links. Particularly with the way I organized my own Puzzle Pointers, it's easy to see which puzzles I've done.
If Black Ink had a visual representation of current and recent puzzles that showed where I stood, I'd use that. If it supported puzzle subscriptions in the style of RSS feeds, I'd use that. And if it quietly cleaned up aging completed puzzles, it would be a better housekeeper than I am.
And -- quite off-topic -- I think this local constellation of crossword enthusiasm is very curious. Will Johnston is in Watertown, Red Sweater is in Somerville, and I'm in Arlington.
Strange - must be something wrong with my internet connection. I can access your site from a shell account on my web host's machine, but not from my Mac.
