Is a question ever so simple that answering isn't considered necessary because the answer is readily available, e.g. via a web search?
This comment and associated question provides the background for asking this.
No a question is never so simple to best be left to a google search. Most of the questions posted here so far are also covered on the web, if not all of them. The site is supposed to be a collection of all homebrew questions and a ranking of the valid answers as voted by the community. When you do a web search for an answer you have no idea to what level of confidence you should accept that answer. StackExchange lets you see exactly what a community of like minded people think of an answer.
