I'm a first year student in Computer Science and we all have big problems with math here. We study real analysis, elementary set theory, linear algebra and discrete math and we seek help wherever we can. I decided to give math.stackexchange.com a try, and this site saved my sorry butt numerous times already. I told my friends about it, but then I realised that perhaps inviting even more clueless students, who only ask questions and don't really contribute anything to this site, is not a good idea? I'm really, really grateful for the community of math stackexchange and I don't want to do something wrong to it.
Edit: to make it clear: I confess to being that kind of student. I ask only questions here and I can't provide any answers, even though I try. So that's why I assume my colleagues would act similarly, and I don't judge or blame them for that.
So, tl;dr: is inviting more students (who will only ask questions) to math stackexchange good etiquette?
