It's been said already, but I think it's mostly the fact that it's fall now, since I feel like most of the members here are in the 14-22 yr. old age range, and most of us have to go back to middle/high school or college. On top that, when there's no new pairing moments to talk about, people tend to post less.
For me personally, I guess I don't really post in the Debate Thread as much anymore, since I get tired of repeating the same thing over and over again. It's interesting when we have S/S or N/H fans come here, since it spurs new conversations, but I guess I don't like to bring up the same points repeatedly. Some of our veteran members are usually alright about reiterating points to help answer newer members' questions, but I don't like to post if I can't put a new spin on something I've said already.
That being said, I actually feel like this site's been busier the last week than it usually is. The thread for the last chapter has over 15 pages now, instead of the usual 5 or 6. And like
tricksie said earlier, there's actually been a pretty big influx of new members in the past month or so. Which is surprising, since there hadn't really been any definite pairing moments in the anime or manga before last week. For example, I joined this site after seeing Sakura's confession in the anime, and I know at least three semi-regular posters here joined within a week of me joining. I'm not sure if it was for the same reason, but I feel like pairing moments do tend to facilitate new members joining this site.
