Someone recently posted a picture of a piece of food preparation equipment and asked if anyone knew what it was. While I'm glad they found an answer, questions of this type are really only of use to the OP and do not serve the internet at large. If someone else wants to know what this thing is, what could possibly lead them to this question (and answer)? If they don't know what it is, they won't know what to search for.
How should one react to a question of this type? Vote it down? Ignore it and be glad at least one person got an answer? Questions like these don't seem to be a problem yet, and perhaps they never will be, but I'd like to hear people's thoughts.
