It is life. Things change.

The internet has changed in the last 20 years (it was once new and cool to use is now so ubiquitous we have to find leisure time else where?)
Forums have changed (no they haven’t, yes they have, black is white, you cannot have that experience without it agreeing with mine, armchair experts and keyboard warriors….tiresome)
Companies change
Our hobbies change
Priorities change

Without really much consumer oriented new products for the last 5+ years there isn’t really much to drive new discussion. So people will find discussion elsewhere.

It may all change again.
