Ask is a search engine too, plus sometimes people like personal answers, or want different perspectives. Not to mention, not all questions can be properly answered by a search engine if it requires an experienced based answer.
Don't really see the point either of being upset if people are using the site the way it was intended, no matter what they are asking, or how easy it might be to search up the answer for. Pretty sure Ask is happy they are using the site to get their info as well (or they wouldn't be in business). XD
