Right now we have the following at the top of the FAQ:
What kind of questions can I ask here?
Computational Science - Stack Exchange is for for scientists doing science by heavy computations.
I think we should change the phrase "doing science by heavy computations". It isn't clear to me exactly what "heavy computations" are -- do you need to be running on a petascale machine to do "heavy computation"? Furthermore, I think that the site should not exclude questions that are not directly related to "heavy computation" (e.g., questions about numerical analysis, programming scientific codes, comparison of algorithms, etc.).
