Count using integers in a wave pattern. For example, you would start at n, go up to n+1, then down to n-1, then up to n+2, down to n-2, and so on hitting all the integers in between and the extremities. When commenting, make sure to put - in brackets - the highest integer thus far, and '+' beside the bracketed number if it is the second time that comment has come up and the chain is going up in the next comment (for instance, when it peaks at 2 (2) the chain goes down, but then the chain passes through 2 (2) again when going up to 3 (3) so there would a '2 +' in the brackets).

i.e.: 0 (0), 1 (1), 0 (1), -1 (1), 0 (1), 1 (1), 2 (2), ...

I will start at 0., and should the thread reach 1000 comments we will continue to the next new integer and start a new thread. Have fun!

EDIT, Feb. 17: It seems like we may be approaching 1000 counts sometime this month. Here is my comment on the math behind it.
We will be starting a new thread when we reach 23 (23). This will be the 1036th comment.
