There is a fundamental problem with StackOverflow and I don't believe they can fix it. Many "new users" of the service view (or want to view) SO as a "question and answer" site similar to ask.com or Quora. I don't think this is unreasonable at all as even Google will suggest that SO is one of the most popular question and answer sites on the web. This flies in the face of the desire of SO leadership, many of its moderators and, the "old guard" to have the site be a curated programming resource akin to Wikipedia. This is also not unreasonable. The rub comes with SO desire to invite questions to be answered rather than soliciting tutorials or documentation akin to how Wikipedia works. SO even had a failed attempt at exactly this (SO Documentation). In essence, they (SO) want the benefits of both models while not recognizing the irreconcilable conflict. New users find the community hostile and belittling, seasoned users find questions condescendingly trivial and repetitive. This particular issue (highlighted by the OP) should be of no surprise to anyone familiar with SO and the semi-annual crisis of identity they seem to have. A new user posts a first time answer that is not of high quality (principally the name of a library and a link to an off site documentation) with no real (SEO) value for SO. Then, rather than given a chance to fix things, their technically correct answer is deleted by a moderator. Note, the moderator could have edited the answer to expand on it themselves but rather chose to delete an otherwise correct answer from a first time poster.
