To whom it may concern:
Please, leave a certain user alone that used to regularly post on Physics Stack Exchange. Stop whining and crying about it, and act your chronological rather than your social age. The site is doing just fine without him, and new stars will always appear to replace the old ones. The site is meant for users of all levels from highschool to research level, so it's not being downgraded at all--unless you want it to be a physics equivalent of Math Over Flow.
If you find the place too painful and unhealthy then just leave. No one particularly cares about you, anymore than they do about me or anyone else. It's just a place where people can ask and answer physics questions.
OK? Good. May your time be filled with lashings of physics, topped with more physics delights. Have a nice day :)
