August 1, 2000: Gamasutra has an article up on the difference between casual and core gamers. I found the article only ok, but I think it's a worthwhile topic with relevance to web (or any software) design. I think it's probably closely related to the old ease vs. efficiency idea problem in interface design. And it all comes back to asking who's gonna use your site (or software or game) and how they're gonna use it.
