There are many reason's why this site could be "petering out".
One of the main reasons is that you have a lot of people (myself included) talking about non martial arts topics.
Another might be that every time someone posts something, they get blasted and called a bunch of names. Instead of having a decent conversation, they just trade shots across the forum. But that's what makes it so much fun....
Another reason is that FlyingClockChoke is a freakin' communist idiot!
But those are just my opinions.
