Is it worth coming back?
Back to the Future? 
If you are expecting to find better forum than it was few years ago than I don't think so.
More OG members left the forum, theymos banned mixers, and conversation between members is not getting any better.
You can however select topics you like and talk with close circle of like minded people.
Obviously how things work here. No wonder I go mostly unnoticed
The OG members have close friends they interact with and easily give out merits to.
Sometimes, you don't need to interfere in any board they are discussing because you could easily be ignored even if you made some senses. The world is indeed not fair.
