Not quiet dead yet, but yes, far less people visit that in the "hey days".

Simple fact is that many vB3 & vB4 owners already have all the mods they want, and there is virtually nothing for new vB5 owners.

People are still buying vB5, but installing vB4, so there is a need there, some people on vB3 are moving to vB4, so a need there.
I expect it to be around a few more years yet, but this will never be as busy as it once was (unless something totally unforseen happens).
