The forum's statistics seem to completely disagree with you.
If we look at the statistics page:
http://forum.blockland.us/index.php?action=statsWe can see that December was a third-of-a-year high in terms of posts/topics.
We can also see that January is on record to blast away december in terms of posts, having ~5475 posts in just two days. If we extrapolate by multiplying by (31/2) we come up with a number of almost 90,000 posts, indicating that people have been posting FAR more often than before.
So in other words, it's just you.
