The use of language on the forum is dropping also, mostly among some of our regulars.
Some people (such as myself) find cussing neither enlightening nor useful as helpful banter.
There are a lot of people signing up here and expecting to get a effortless and complete answer with no other questions asked. Then, there are even a few people who will start flaming when they have to do something, saying words much like the ones Duoas started seeing fewer and fewer of. Oh woe...
EDIT: Fixed a few grammar errors. Geez... I need more coffee...
