Downvoted good questions or answers on StackExchange (superuser, stackoverflow)

I don’t understand what is wrong some of the people in this StackExchange community. I have seen very nicely worded questions and to the point answers downvoted. I know this is not always the case. Bad questions gets “rightly” downvoted and good ones hardly get “upvoted” and I am “fine” with that.

Anyways. What can I do to survive these answers and questions? I cannot upvote them as I do not have any points yet because I haven’t asked any questions. My friend from the university has an Stackoverflow account and I send the links of some of the downvoted questions and answers and if he regards as them worthy of upvoting he does it. But I need more people like that.
