lol. so theres a lot of people on the forums, but how many people post new posts and stuff... i still feel like there are never any new posts anymore
Ignore June since we're only slightly over a third of the way through it, but compare the previous months to each other.

There is certainly an obvious decline in number of new topics made from one month to the next, but that's to be expected considering topics don't need to be created multiple times, so once a thread has been created, there's no need to see it again (sure, it happens, but this will still lessen the number of new threads over time).
Also, the decline in new topics is far more drastic than the decline in new posts, which hasn't really declined too severely (only about a 10% decrease instead of a 30-40% decrease that we see in new topics), which also helps illustrate my first point. Activity has only declined a little; there's just not as much new stuff to post since things can only be new once, and after that there's no point in repeating it.
So, yeah, there's decline, but hardly enough to be so drastic as to say the forum is dying.
