I've noticed across the internet; forum traffic as a whole is down.  Car forums, computer forums, gun forums, other hobby related forums.
People blame it on facebook; but I definitely don't see the board traffic on there.
I don't know where everyone is; or what they are doing now.  It is disconcerting though.  I've been on some forums for over 10 years and the drop is somewhat recent.
In 2008-2009; I first noticed a dramatic drop in forum traffic on the performance automotive boards.
Ghost towns. Are that many people really watching that much TV these days?  What else could they possibly be doing?
The state of the economy reminds me of the 1970's. At some point; people are going to become bored and get tired of doing nothing and start doing something.
I've already seen some signs on other boards of people thinking outside the box and attempting to create new things to do.
