I believe it is an acknowledged fact that with the popularity of the site the volume of traffic and new puzzles has strongly increased. While this is generally good, it also means it becomes increasingly harder to "catch" interesting/hard/creative/you-name-it/etc. puzzles if you're not checking regularly.
This is a known 'problem' and there have been several suggestions discussed and some action taken. Things like the Fortnightly Topic Challenge and the Best-of-series try to deal with this, but they both have their advantages and disadvantages. The first is more of a challenge; i.e. it does not look into existing puzzles and does not add puzzles once the time is over. The other is both highly subjective and also limited in the amount of listed puzzles. Also, it is not easy to browse for a specific 'type' or 'meta-type' of puzzles that way.
A lot of (new) users to this site are likely wanting to find "Good puzzles in the style of..." or "Puzzles which are long/complex/whatever/..." and it is not easy to browse with that in mind.
Should we start a curated post here on Meta which provides meta-tag- or property-sorted lists of hand-picked puzzles?
This could serve as a 'sorted' entry-point to new or returning users. The style would be similar to the Fortnightly Topic Challenge, but the "grouping" parameter would not be a tag, but some non-taggable property. The post(s) would also be continuously expanded on (as long as the community cares.)
I'm aware that this is, to some extent, a step 'backwards' (like hand-picked link-lists vs. Google); I'm not suggesting this as a replacement but rather as an accompanying feature. I also think it is in the interest of the site to have a "growing" legacy of some sort, and hand-picked "jewels" of puzzles (or 'bad-examples' or whatever!) can be better found that way.
What do you think?
A potential format of these posts (to be discussed) would be that each has a clear title like, for example:
List of Puzzles that property....
- List of Puzzles that require a lot of work to solve.
- List of Puzzles that are good to use in RPG adventures.
The question then defines in more detail what the property is (if needed) and answers contain a single link plus some comment similar to the 'Best-of' posts, allowing others to vote on each entry.
