It's inevitable that all of us will eventually stop posting, for one reason or another. Your circumstances or job change, or you simply lose interest in internet-based discussions... many people register, then only post for a few days before disappearing again. This forum has 8,463 registered members at present; many hundreds of old accounts have been pruned, too.

That means that a good eight thousand or so people have simply stopped visiting EoFF.
It's no big deal, really. You can't expect everyone to love the place.
Some take a while to decide it's not really their thing.
Some just feel no attachment to the place and don't care about posting.
Some feel too much attachment and become distraught every time their "second home" changes in a way they don't like, so they leave too.

I'm in favour of a happy balance - posting for enjoyment and to meet interesting people. Not making EoFF the foundation of my life, but not neglecting it either.
