I am in this same frame of mind. When I started out in development I quickly found how unwelcome my questions were. The thing these mods and many other higher rep users are forgetting about is that to the new person these not a dumb duplicate questions. If a clearly new dev(and if you are not new yourself you can tell a new dev from a mid or senior level) asks a question that is truly a duplicate in every way, a little good faith that they do not know what they do not know to the level that they did not realize I think is not to much to ask. Apparently for some of these higher rep people it is.

Further if it is actually a duplicate what harm is there to leaving it open with a link to another question that has an answer? How many times have you looked at multiple SO questions and answers to piece together something that fits your very specific use case? For me it happens that way more often then not.
