Having an older, generally more mature member base here is something I enjoy. I’d rather see the board fade away than be taken over by youngsters.
I used to enjoy Mythbusters forum, but it was closed before the series ended because it was overtaken by too many youngsters asking for the hosts to do easily answered “myths” and crying “But I want the Mythbusters to do it…wahhhhhhh!”. The one that made me glad the forum was closed was an admitted preteen (the lower age limit was 13) asking if blowing on a spoon of soup cooled it quicker than not. A number of scientifically sound answers were given, but the poster still replied with the above wahhhh…statement.
