"The responsibility for keeping threads from becoming boring relies on the kind of participation given by its posters."

True, but again the term boring is subjective.

I recall a person who put up animal pictures and invited people to add captions to them. Some people found if humourous, while others found if trivial and boring. The latter folks had the option to not open the thread and pass if by. But, some of them felt it necessary to go intk the site, to make rude comments. Theh eventually had their way, and bullied the woman from continuing. Now, what was thd gain in doing that, beyond imposing their subjective views on others and taking a small bit oc joy away from others.

You may see this as trivial, as others may find your interests the same. These judgements are subjective. Getting along means being respectful of a variety of perspectives- not just in the religious, political, and sexual orientation threads.
