On more than one occasion, I have created a puzzle, usually putting lots of time and thought into it, and it doesn't get much attention and/or it isn't very popular (according to up-votes). Sometimes I realize that it's just not that good/interesting of a puzzle, or too difficult, but more often, I think the idea is cool, but the way it is written could be improved and/or the type of clues given and number of clues given needs to be adjusted, or the format needs to change, or something else could be changed to improve it.
Here's my idea: It would be cool if there was a team of trusted users who could opt to be a critiquer for any specific puzzle (completely optional, puzzle by puzzle). I realy feel like I need a second (and maybe third) set of eyes to at least sanity check, and usually more. A very recent example is this puzzle, which I think could be great, but I wonder if it needs more clues, or clues from a different angle or perspective. I'd love to be able to show and explain the puzzle to 1 or 2 or 3 experienced (and willing) puzzlers who have agreed to be able to be asked to be a critiquer, and get their feedback and/or suggestions. All critiquers wouldn't be able to see all puzzles that asked for critiquer help, but only the specific puzzles that they agreed to critique. Of course, the critiquer would not be allowed to answer the puzzle, or comment on the puzzle until there was an accepted answer.
I don't know if this site can provide this functionality or format. Maybe it can. It would help me become a better puzzle creator, and solver as well, I think.
EDIT: Along the same lines, a variation of this could be, the puzzle creator could opt to release his puzzle to a "test audience" of 3 or 4 willing trusted users. If it's a hit there, then consider posting it, else consider requesting it to be critiqued.
