I hear what you're saying, and I've had the same kind of thought myself.
However, I've received feedback over the years from people who participated in (or tried to, in any case) different kinds of aikido communication venues. One piece of feedback that I received was that some folks wished there was a way to communicate with other "experienced" people. I wanted to create that venue but still keep it "public" in the sense that the general public could read what they were writing.
There's nothing preventing anyone, of course, from starting up the same kind of thread in the other forums and inviting the experienced folks into it.
As I said, the "Voices of Experience" forum is something experimental. I'd like to see where it goes before I label it as anything.
Thanks for the thoughts, in any case. Anyone else?
