While I agree with everything you said, and consider this a great post. I would like to make a point about using the search function here. It has A LOT to be desired as a tool for newbs. I used it quite frequently while researching for new headphones, and when I would try to get posts for my topic, it was far from anything relevant. I have seen other posts, though not many, that have said the same thing. One helpful one I read was to Google your topic, as this was a better method for receiving the posts you were looking for.
I think that the search function is most likely underused, but it could be made better to get more use. Other than this issue, I have found loads of information on this site, and continue to do so. If all newbs would read this before asking the proverbial, what should I get for $100, we would all be happier.
