There should be no doubt that discussions on the RG are a part of research activity. 1) It is discussion between academics in a dedicated network, 2) the subject of such a discussion is connected with their academic work, 3) the discussion sometimes includes a 'mentoring' factor when you show younger colleagues tracks for their research, moreover 4) the discussion is recorded. Do you think that such an activity may be taken into account when you evaluate somebody who applies for an academic title (like a PhD candidate)?

In applied social sciences (such as city planning) is common to use questionnaires to assess housing, transportation, services ... I believe that the answers on RG may be considered as these questionnaires.
About the experience of those who answered the question, is part of the questioner evaluate the response content.
But I I believe that the contribution should not be measured by the level of education or the number of years that person has the title (MsC, DSC, post doctoral ...).
