It was a lighthearted suggestion Eloethan, which I thought might help readers decide if the subject being discussed was at a similar level of understanding /interest as their own .Some posters seem to attract a lot of criticism of their opinions ,not based on their said opinion, but because it’s is not written or delivered in a manner to others liking .I thought again lightheartedly, that it would stop some unnecessary put downs, which detracts from the subject. I avoid commenting on some topics, because I don’t know enough about it.As it is an Opinions site when I do join in but it can be tiring to have someone focus on how you said it,rather than what you have said. Why not just ask the question, what did you mean? Courteous & simple.
