Rätselportal <-> Sudokuportal

[CHalb]

Is there any site or such that caters to ... I don't know, "previewing" puzzles?  Throwing it out to a group of profiles that try it out and give responses - which would then give me and other experimenters an idea of what grabs interest and doesn't?
...
So I'm wondering if there is a site/portal that functions almost like a curator process, so I could learn which of my offbeat ideas will gain an audience ("Battlefield") and which ones will get mostly passed over ("Virus Sudoku").  Or if that is a non-starter idea.

I don't know any specific site or forum for this purpose. But three thoughts about this:

1. Many of us gained over the years contact to many puzzle solvers and authors. I personally send almost each of my puzzles - especially the more complex ones - to one of my puzzle friends and ask if they can test it. But by this I do not get feedback before publishing from many people (max. two if the first one doesn't answer fast enough). Yet my experience - and own habit - with test solving is, that we do not only respond how many solutions the puzzle has. But in many cases we give a feedback to a lot of aspects of a puzzle.

2. You have experienced yourself a bit about this forum. Sometimes people ask here in new threads for test solvers without revealing the puzzle itself immediately. This may be shifted to ask explicitly for overall feedback.

3. I think the portal is a very good place to show a tested puzzle to many people and get feedback. Even if the puzzle maybe does not get a high rating in beauty: you can get diverse feedback and you never know, what it might trigger in other people. Many of my own puzzles ideas have been initiated by other portal puzzles (and sometimes by not reading or understanding the instructions properly   ).
