Why was there a sudden spike in activity for the last few months, and then a decline?
Are you talking about sexual activity?
Is there some posts per week graph that I'm not seeing? Or should I be randomly sampling the date of every 100th post number?
I don't have a graph, but Today seems to be very slow for nesdev. Just a couple weeks ago, it was crazy how active this place was.
I had a science project, so that could be part of the problem. 
I secretly placed a banner link to this site and then also removed it. Hahahahah

I would reword this as a "constant level of activity for the last few months, and then a sudden decline."
If a few months counts as sudden, then one week is quantum.
(Sampling, as tepples suggested) The past 2600 posts have been spaced fairly uniformly, mostly averaging 3ish posts per hour.
The oscillatory behavior that shows up is almost certainly aliasing against time of day.
