I have been curious about this - I see a lot of prior art requests that get posted and I/other people have been answering some of them. I think it's great to have visibility on some of the prior art requests that reach the PTO. Several of these requests come from the same group of individuals.
How exactly are those answers used? Are there actually USPTO members on here requesting prior art information as part of the patent publication process? Are there people prosecuting/defending ongoing patent cases? Or is it some kind of non-profit organization or individuals that are trying to make the patent world better?
I did check the "about" section and couldn't really find any information.
