Er... sorry, but I don't buy it.
A while ago, in this thread

I asked if anyone knows anything about the quantum efficiency of Te and Mo. I had responses, including a few via PM. Since then, I've used what I got from here in my work, and then published papers on it. Now, according to you, this is "proof" that a discussion in PF can actually result in a significant contribution to physics. I find that to be stretching it quite a bit. We could easily extrapolate it further by arguing that many of the students here will inevitably be affected by what they learn from PF (especially if the seek HW help), and if they become physicists later on and make an impact in their field, then PF discussion has just the same thing!
No one denies the value of PF here. If I find this whole endeavor to be useless, I wouldn't have stuck around. But what you are arguing is that research front work can, as a rule, be done on an
open, public forum and can typically result in a significant contribution to physics. That is what I argued against. I also run a private Yahoo group for the research project that I am involved with, where memberships are by invitation only because we are discussing yet-unpublished data or future projects that we will be doing. Many of these have resulted in publications, and in fact, one such work that we discussed resulted in one of our group members to give an
invited talk at the last particle accelerator conference this past June in Albuquerque. But you don't see me running around proclaiming that Yahoo Groups as a valid "research" avenue or source, do you? We could have easily done it via e-mail distribution (which, for some people, was what it was if they subscribe to the Yahoo group that way). But the fact that it was highly contained and heavily moderated means that this isn't your normal, open forum. PF is the latter, but you are using your "evidence" to suggest that it turns into the former.
Furthermore, I don't quite see what the point to all of this is. We already have the BTSM forum for people to discuss such things, and anyone who wants to try out their personal theories that haven't been published can do so in the IR forum. It's not as if we use the IR forum to publish crackpottery.
I still maintain that what you describe occurs extremely infrequently in an open, public forum. When when it appears to have occurred, I find it a real stretch to actually attribute it the way you have made it to be, and certainly does not justify the creation of a whole forum.
