Thank you Analyzer and 19narvik40.
Why do you think the subject matter is some of the reason why there has not been any comment?
I have noticed in the past few years a decrease of comments in some threads. My guess is that our society has become a "symbol society" - there's a symbol for everything as if we could not read anymore... Theme parks are filled with symbols, our micro-waves, freezers, washing machines, etc. FB and IG have in part been responsible for that "symbol culture", almost as we could not express ourselves anymore without a symbol (rather sad actually...) So I think maybe it's a lot easier and faster to leave a "like" or a "thank you" instead of writing something down. Don't get me wrong "likes" are important and a sign that the thread as been seen and appreciated however I believe a forum is not a one way road. There should be interaction between members to keep threads (and the forum) "alive".
Anyway thank you for your opinions and "likes".
