I know from other StackExchange sites, that please identify this questions are unwanted. The most cited reasons are from the Let's Play the Guessing Game blog entry.
You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.
A half-remembered description of something you vaguely recall is not what I’d call a practical, answerable question.
Because these questions are based on vague, broad, half-remembered descriptions, it is unlikely anyone else will be able to find them through a web search. I have a difficult time imagining how you’d construct a web search, either on Google or via Stack Exchange’s built-in search, to find something that you can’t fully articulate. What’s even worse is that these questions, by their very nature, will contain a bunch of broad, speculative “maybe it’s like…” catch-all terms that are likely to trip up future visitors who end up there by accident.
I understand that it’s sometimes fun to guess what someone is thinking of. I also appreciate that it takes a lot of expertise and deep domain knowledge to take a vague, half-remembered description and nail the exact thing. But I would also argue that these questions aren’t educational in any way, because there’s no way to learn about the process of discovery.
I am asking because this question was asked, but would like your opinions not only based on that one, but if we want those kind of questions is general. I personally agree with the points Jeff mentions in the blog post and would like to ban those kind of questions here, too.
