I think this is fundamental to a For Beginners forum. Beginners tend to lack the skills necessary to find and evaluate information. Indeed, often they don't understand how to take general advice and fit it to their specific situation.
I think the answers to these questions actually do change, albeit slowly. While there is never a correct answer to "what language should I use", there are languages that you can use today which wouldn't have been realistic five or ten years ago. Something like XNA or Pygame can be the difference between a strong recommendation as a starting language and a more dismissive "sure, if you really want to". FAQs tend not to be maintained as one hopes or imagines.
They can be wildly optimistic about the kinds of projects that are feasible, and what a team cobbled together are likely to achieve. I'm not sure how to solve that problem, experience is the most likely deterrent. At least classifying and separating such projects separately helps them from drowning others, and having some kind of barrier to entry (e.g. a mandatory project template) can help prevent that idea a newbie thought of two minutes ago becoming yet another entry on the forum. I've not seen too much of this lately but I don't follow the classifieds, so maybe it is still a problem.
No, it isn't fun answering what seems to be the same question over and over. If you don't like it, as others have said, you can ignore them. In any case, during the summer break there is a lot more than the rest of the year, chalk that up to the younger folk having more free time. Kudos to them for using that to try something new!
