Have a look at the discussion in the last few comments of this question: How to weight pedals? (Not picking on this question, just using it to illustrate a situation.)
In the case of a question that's more along the lines of I-need-ideas-to-do-foo (as opposed to how-to-do-foo, which is a different question), is StackEchange an appropriate way to go about this? I have in mind a case where a user needs ideas to try as opposed to the answer.
Is this what the community wiki function is for? Or is this a question we should kick over to regular forums? (I'd rather not do that, but it might serve the person asking the question better.)
