I still think this is the most helpful site for all things "PS3 related".
I think it really has to do with the "lack of advancement" (ie, no 3.56+ CFW) in the scene.
That has a tendency to make people anxious and frustrated.
That's when the bickering starts. Once that happens, the "old timers" just kind of kick back and stay away for a while.
No real sense in watching the same arguments continue to get hashed out week after week.
I have been on the net since it was basically nothing more than a bbs and have watched this happen in quite a few instances over the years.
Hopefully the recent rule changes here will cut some of the crap out.
I'm all for a little banter back and forth (such as what we had at "the groove" with a few of the members (remember Turkish )) but when it gets out of control, respected members have a tendency to go elsewhere for a bit and let the children settle down and take a nap.
I hope somebody has a good response to your question and points you in the right direction.
I would much rather go to my grave not needing my gun, than go there wishing I had it.
