I think handling these as cannonical questions is the way to go.
Looking at the current answers on the post that started the discussion, each of the answers seems to me like it should be it's own question.
Doing so has the following advantages in my opinion:
- Each "problem" can be located on its own, rather than having to scroll down a wiki post.
- Each existing answer seems like it could be an end-point for the "Close as Duplicate" option.
As an example from the posted question, I would ask the following question and question body:
How do I make sure a bike fits when purchasing in person?
I'm look at buying a bicycle. It may be either new or used, but I will have a chance to test ride it in person before I purchase it. What do I need to know and check to make sure it fits?
In this case, the answer would be most of the links that are included in the current answer here.
Using the cannonical question format would also help with some of the canned comments that many mods and high-rep users fall back on when we see similar posts. On example I use all the time is when closing as a product rec I frequently add the comment:
Product recommendation questions are generally a poor fit for a Q&A site since the answers quickly become out of date. There are a number of previous posts that will help you know what to look for when buying a new/first road bike link1, link2, commuter bike link1, link2 and mountain bike link1 link2.
These could then be either closed a duplicates, or still closed as product rec but linked in the comments to the relevant cannonical question.
