I very much appreciate that math.se is designed for users for all levels, and I think that I really gain something from interactions with users of higher and lower levels of mathematical sophistication than myself. However, I sometimes get frustrated when I am looking for an answer to a more sophisticated question and have to slog through pages of similar but lower-level questions. For example, I was recently looking for information on the existence of solutions to general systems polynomial inequalities, but came accross mostly questions like this one or this one. There is nothing intrinsically wrong with these questions, but they are more basic than the ones I am after.
This leads me to my question: should tags be added to indicate not only the subject area of a question but also the level of sophistication? I feel that this would not only make it easier for people to find answers searching the site, but would give answerers an idea of the level of sophistication of the questioner so that they can gear their answers accordingly. Of course, it does have the downside that sometimes questions are actually much deeper than the questioner believes. I have tag creation privileges, but I figure that this move would require consulting with the community.
