I think it's rude that people who are capable of reading expect others to do the reading for them, and hope that people would bring them information anytime they ask instead of using the wiki for its actual function.
Imagine someone just lazing around all the time and keeps asking you to get up and get things for them when they are totally capable.
Maybe you might like holding their hand all the time, so you can be in charge of answering all their questions. Don't leave them hanging too long though, because I imagine they want their information as quickly as someone who checked the wiki, as some like to think asking the discussion board is faster.
I mean, someone does answer them eventually, but usually incomplete or at times incorrect answers because they were answered by other people who can't be bothered checking the wiki. You can help fix this by reading the wiki articles for them and making sure they get the best answer possible.
