There have been a few puzzles lately that have intentionally omitted tags because the existence of the tag would spoil the puzzle. It makes me curious as to whether the tag system works for this site.
For puzzles which do NOT omit these tags, by nature it means that you can eliminate some potential answers by process of elimination. And when someone does mention "I omitted a tag for a reason" then it narrows down the search for clues significantly.
People who like cryptogram puzzles should be able to search the cryptogram tag and find all of them. Intentionally hiding the tag seems to be counterproductive, because you're cutting off some of your audience.
But I don't want to get into a debate about whether or not that approach is right because that's going to be a matter of opinion and we shouldn't chase anyone out of the community for simply doing things a different way.
Instead I want to consider a better approach to this.
Perhaps we can set it up to where we can have a "hidden tag" puzzle, where when someone finds out that it's a cryptogram and posts the correct solution, and that solution is accepted, the cryptogram tag becomes revealed? I'm not certain how complicated this would be on the back end. But it seems like a great way to give tag-hiders what they want while still preserving the usefulness of tags for the community.
for example, there might be a puzzle labeled wordplay word 2-hidden-tags in which finding out the tags is part of the puzzle, but when the puzzle is solved and a solution is posted, the tags automatically change into wordplay word cryptogram leagueoflegends.
If we do this well enough, hiddentags could well become a favorite tag among people who come to the site, especially if they like most forms of puzzles and like the sensation of figuring out what kind of puzzle it is.
