Alexei, I agree with you on "class 2" questions. But on "class 1": Sometimes even these questions, for whatever reason, spark a response from one of the great people at Wolfram or the really experienced and knowledgable people in this group - and sometimes these responses frequently go far beyond the minimum required and explain something really interesting about Mathematica, or programming in general, or algorithms, or who knows what. I'm willing to read a bunch of similar answers (and even a few rants) in response to the "class 1" questions on the chance of finding one of those exemplary answers. Now, you mention that you'd rather just point to how to get the documentation in those cases: I think that is appropriate. But one hopes that the documentation writers - or dare I suggest, usability specialists? - at Wolfram are paying attention: if the same kind of question is asked often (as has been noted in another thread recently) then there's something inadequate about the current help/doc/error message/usage message system. (For example, this group gets a lot of questions from people who don't understand a particular error message. It has recently been noted that usage/error messages can contain any kind of formatting. Why don't more of them, then, include hyperlinks into the doc center? For another example, there are also a lot of questions from people who don't understand why they got a particular error message in a particular context. Maybe there should be a package (optional for experienced users!) that, when a message is issued, analyzes it and the stack and tries to figure out some context-specific help. (It might require a hook similar to $NewSymbol which is applied to the whole message, unlike $MessagePrePrint which is applied to only expressions included in a message.)
