I agree with you that FB has diverted the information--free posts from specialised forums, but in my view, people spend much less time on forums, where the personal recognition to whatever you post, is very limited.
I had a nice experience with the flashlight forums, where I made thousands of posts in their heyday, when the LED replaced filament; it was entirely constructive until the arrival of the Chinese, who sucked an immense wealth of specialised knowledge - entirely for free.
It changed my approach to forums forever.
Thanks for the exchange. Looking at a Paranormal mod now, one that I don't absolutely need, but looks awesome...
