I think the Wiki has been slowing dying for a long time. Of course it has to do with users growing older and moving onto other aspects of life, but I think the whole Brickimedia event had a role as well. The community was threatening to split in two, causing some people to leave entirely. The constant presence and interference of non-community members affected the environment. The whole affair sparked a remodeling of the WIki government, drastically changing the culture and causing even more users to retire, especially those accustomed the old way of doing things.

That's just one factor, but I think it was a significant one.
