This is an interesting role-playing-game set in current-day web forum culture:
It's somewhat not-safe-for-work, and the humor is pretty low-brow. But what's neat is that you play it through your browser, and it recreates the look-and-feel of web forum culture perfectly. It wouldn't surprise me if the authors just captured the HTML for various real-world forums to create the resources for the game. (Or alternately, created their own fictional forums using web tools, and then captured the HTML from those fictional forums.)
The actual game didn't hold my interest for very long, but it's free and it's fun for a few days.
