ohhh noooo, usually it is quite easy to spot what is a tedius waste of time and totally pointless. If I get that impression I don't even bother clicking on it. Actually it is also a good guide to check out the question author too, that tends to dictate the content. : ))
Sometimes you have to click to find out what the heck the question is, especially those where (1) the heading doesn't give a clue to what the question's about, and (2) the actual question is hidden from view by a great long intro, such as ''Sorry if this is under the wrong topic but I'm new to AB and don't know if this is the right section to put my question in, etc, etc....'' ;-)
