I don't know if the following trend speaks about the average age of posters or not. But there has been a definite falloff in the quality of questions being asked in the last couple of years. Not only are the same questions being asked over and over but some show a definite lack of observation by the poster. As an example, (obfuscated as much as possible to protect the guilty) a recent poster was blaming a certain film for effects of light that anyone with a modest amount of acumen would know are perfedtly natural. Does anyone still really look at a scene before they trip the shutter?
