That’s probably when people are like “I will rather wait for another open thread, so my comment has more visibility”. If we will have open threads more frequently, that moment might just come sooner.
Posting near the end of an open thread’s lifetime is (maybe) like cooperating near the end of an iterated prisoners’ dilemma: others benefit (by having interesting discussions available more of the time) but you lose (by having what you post seen by fewer people).
One way one avoids this in IPD tournaments is by making the end uncertain (e.g., each turn after the 100th there’s a 1% chance that the game ends). It would be interesting (though, frankly, probably not worth the effort) to randomize the starting of open threads in a similar way: e.g., once 3 days have elapsed, each hour a new thread gets started with probability 1%.
Could you add labels so stupid people like me could figure out what that graph means? I’m guessing the blue line is top level comments and the green line is total comments; both averaged from all the weekly open threads. The y axis would be number of posts and the x axis should be time but I’m not sure what unit it’s in. Also, why does the blue line suddenly stop?
The blue line suddenly stops because the last comment is posted at that time. I was kind of lazy about this graph and did have labels and a legend, but apparently I was too out of it to realise they didn’t show on the png.
So I did what you suggested and plotted the number of top level posts and total posts over time. The attached graph is averaged over the last 20 open threads. Code available here: https://gist.github.com/TRManderson/6849ab558d18906ede40
I don’t trust myself to do any analysis, so I delegate that task to you lot.
EDIT: Changed GitHub repo to a gist
For those who don’t want to guess or dig into the source, the missing x axis unit is “minutes”.
In other words, open threads die after about 4 days.

However, I am in favor of an experiment.

As said by gwillen, x axis is minutes.
Sorry about not having units, I added code to set them but apparently it was the wrong code and I wasn’t paying enough attention.
Green line is total comments, blue is top level comments. X-axis is minutes, y axis is number of comments.
