If you perceive a question to be silly, don't read the thread. Let someone else handle it. There are many users in this community more than willing to assist.
I respectfully disagree with this approach/philosophy and it carries over from my issue with the silly thread in the other forum. I would hope that we all want to keep the knowledgeable folks engaged in helping solve the more difficult questions for the community and not burnt out by having to sift through silly questions and off-topic humor. The quickest way you are going to lose those folks is by allowing the forum to fill up with a lot of crap that isn't worth their time.
By all means if the majority here doesn't really care about keeping some standard of organization (i.e. a separate forum for off-topic posts; moving specific posts to appropriate forums),or if they lose a few of the more dedicated and knowledgeable folks who get tired of sifting through the same old questions that people could have answered themselves, (and adopt a 'someone else will always answer the question'), there is no doubt the community will persist - but my guess is the serious, dedicated people we want to keep engaged will ultimately feel like there is no need for them here any more and get tired of it and their attendance and participation will be less and less. I've seen it before elsewhere and suspect its just par for the course in any internet forum - I'm hoping we are better than that.
When I first found this forum, maybe it was a mistake on my part, but it sure seemed there was a lot better signal to noise ratio than there appears to be now - I guess I was mistaken.
