I'm definitely not of the opinion that there is no place for this type of question. I do think, however, there are good examples and bad examples of how to go about it.
- Made some work - Need feedback -- Not too bad. OP is asking for feedback about specific aspects of the example. Title isn't helping any though.
- Game trailer feedback? -- Not a big fan of the openendedness here
- Feedback please? -- Title useless for searching. OP gives no direction whatsoever as to what he's hoping to get out of the exchange.
- Sound design feedback? -- Again with the title! Otherwise, this seems to be fairly focused question. It's openended insofar as it is just soliciting opinions, but at least there is some background and some attempted focus.
These were just a few of the first examples in a search for "feedback".
Going forward, do you think there should be guidelines/boundaries concerning how best to ask this type of question? I think these questions inherently walk the line between acceptable and "too localized". I think in order to keep them from being useful only to the OP, they...
- Must have a descriptive title? If it's not searchable, its usefulness is severely handicapped.
- Must be asking something specific rather than an openended "what do you think"?
