Someone recently asked how to speed up iterated manipulations of a graph/table and included a (failed) link to an article about why he wanted to do it. It's about something important that has been recently discussed in Seed Magazine, the Publications of the National Academy of Science, and in newspaper articles. What do you think about encouraging people to include a link or reference (when appropriate) with asking a question? I think it would be interesting and informative for SE participants to know what other participants are using Mathematica to work on?
I think supplying a background is often a mixed bag. In some cases, it is useful in determining if the user is asking the wrong question. But, sometimes the background for a question is part of a long twisting thought process where the question is ancillary to the thought process. I think instead of a question's background, per se, we should encourage the asker to address why they are trying to do what they're asking for. This allows us to address methodology while answering the question. Often times, this is the source of multiple good answers where some answer the direct question, while others tackle the approach itself.
