Many times I read questions from Newbies (like me) that are either too basic or which have already being asked many times and have accepted answers (judging from the links shown at the right of the web). Whenever I look up for help, I also find many questions that provide fairly similar answers. If you are not lazy enough, many times there is no need to ask a question at all, unless the problem is very specific or current solutions - having being tried - do not work.
More than a criticism, this is a question about understanding why there is so much tolerance in the TeX network to clear duplicates, not being marked as such. Coming from other networks such as AskUbuntu where the tolerance to duplicates is low, I find this intriguing.
Is it because of the volume of questions? Is it because people come up with their own MWE, which might contain apparent differences - but rather irrelevant - with other posts? Is the ratio of moderators per newbies to low?
Edit: an example (the actual question that motivated this post) is here. A quick search shows 284 questions. Yes, not all related, but the third one (second if we omit the actual post in question) has an accepted answer.
