Suggestion:

Everyone think of a number between 0~9, put it in a bracket (so that it's search-friendly), and add it to their post, e.g. "[7] check out my example.com".

Readers of this thread are then encouraged to search for a random number between 0~9, search for it (e.g., "[5]") via browser, do a few "find next" (just to randomize), and then visit as many results as they enjoy.
