I think a few elders and members of the R&F may come here to actually know more about their own religion. You won't find this level of discussion and insightful writing anywhere near a Kingdom Hall or from a WT publication.
There are adults exchanging ideas and facts here. JWs can't do that at the KH or with JWs who aren't also searching. When I was a mid-teen I was always looking for some adult JW who would be willing to really sit down and get dirty with me. I wanted to learn. I had a thirst for knowledge. My father did not have the intellectual capacity to retain or understand the deeper things the WT taught. My mom was much brighter and could understand concepts far better, but she was more about service and helping the old ladies at the KH run their errands.
On two occasions I actually had deep conversations with an older JW brother. Both times I came away with far more doubts about the Watchtower.
I really believe there are many elders who come here to get a broader knowledge. I totally agree with Jean-Luc that some of them may never be able to leave the WT, but still want to know the truth about the mess they're in.
