Who is a scientist? What qualification would be adequate?

Let's allow multiple methods. Let's say one way would be to have authored an article in a peer reviewed publication. But another could be to have made one or several comments which have received kudos from others or from qualified others. And a third might be to have received an adequate score on some subject related test.

In any case, it would be fairly easy for any reader to select which classes of qualified commenters they wish to read. I hope for one which allows ME to comment despite a lack of official status.
