From what I have seen, forum activity picks up drastically before and after updates and around dev posts. We will see a pickup in activity after Monday's (fingers crossed) planned update, and we will see huge activity around the survey. I think people are mostly tired of speculation on unconfirmed game play mechanics. Many players are in a wait-n-see kind of mood.
I personally am distracted by my work schedule (I promise I will finish those city contracts soon) and by various irl social activities. I fortunately can browse the forums from work on my phone.
