Ian, thanks for your comment.

I suppose I am at the point in my studies, life, and use of social media that I have no idea where the next big, or at least useful, thing can be found. Even things that are superficial can hide little gems at times.

Come to think of it, I think the two of us started to talk in a context where we probably did not expect anything to come of it.

Nice how those sorts of surprises arise and at times last.
