One thing that I have noticed, especially after having been away for nearly a year, is how the mood of the site has changed, ever so slightly. It is just that recently there seem to be a bit more of the "Did you google first, before asking here" type comments (accompanied by a vote to close), in particular to newbie questions, or at least questions from those new to SE, but maybe not so new at 3D printing. I don't remember these types of comments so much prior to a year or so ago.
While I agree that people need to do research, or at least demonstrate that they have done a bit, if people are coming here and asking an honest question (which is not a lazy homework related - and let's face it, there are not many, if any, 3D printer related homework questions) and that question is from someone genuinely interested in 3D printer with a tangible problem, then try to answer it, or at least provide a helpful comment.
Seeing as we are not-quite-desperate-for-users but have an issue with user retention, then we should really not be throwing google in their face - no matter how frustrating a question may seem, or how obvious the answer appears to an old hand. Do we really want them running off to Reddit, or Quora, or Ask (Jeeves) or (god forbid) Yahoo answers, or some other place? Or is it better that we get them to stay here?
Believe me when I say that I know how irritating it can get, I have been there myself. I ended up not spending much time on SE.Arduino, for that same reason - in the end most of the questions started to seem nonsensical, repetitive and idiotic... because I had seen the same topics asked over and over again. I realised that I had to take a deep breath and step back a little - just because I knew the answer and had helped too many people before with the same issue, it didn't mean that someone new would not come along tomorrow and ask the same thing.
Yes, they should have checked google first, and yes, they should have seen the duplicate question had already been asked. However, maybe they didn't have the luxury of time to spend hours googling, or maybe they had not used the right search terms, or maybe English isn't their mother tongue, or whatever. However, it didn't mean that they needed to be made to feel daft.
After all, if someone asks a question here, it probably isn't because they want to wind us up and make us angry - why would they do that? And it can't be judged as lazy, because, let's face it, it takes longer to formulate and ask a question on SE than it does to search for something on Google.
A couple of friends of mine, independently of eachother, sent me this image which, while it made me laugh, also (rather sadly) sums up the "Why are you asking me that?" mentality that StackExchange is perceived as having by the wider techy internet community - this is not a good reputation to have..!
So, all I am trying to say is, when you see a question asked by someone with a rep of 1, be nice and try to encourage them to stay, rather than scaring them off as soon as they set foot through the door. Don't forget it is probably their first question here and are quite nervous as to how they will be perceived (as one generally is when approaching a new group of people and having to ask something).
