I reckon its facebookk n such.
Rather than register on forums people can just slam some words into a facebook group and get an answer.
mainly, people no longer have to interact on forums to have banter with their balling buddies, so less time spent having banter on forums, most posts are educational type discussions on whatever the latest problem with a marker is etc.
The problem is, fb cant archive or have an easy to read history, so the pball groups get the same questions time and time again.
Forums wont be going anywhere, they are much needed sources of information.
me and cooks wouldn't earn those big bux mod salaries either.
