I found this site while looking for something else, but it makes some points that I think are important in the grassroots sciences. The page talks about narrowing the focus of research topics until they are focused and relevant. It gives points to design research projects worth doing. A thought that I took away from this page was that we need to ask more questions that we don’t already know the answer to.
