Recently the following very general question was asked on the main site:

[How do I buy a used bike](https://bicycles.stackexchange.com/q/41040/213)

---

The intent of the question is to be a general community Wiki answer; something to which some of the more common could be linked to as duplicates, and serving somewhat like a FAQ post.

In the comments, on of the mods raised the objection to making it a community wiki and suggested that we use [cannonical questions](https://meta.stackoverflow.com/q/291992/76874) instead. This is an example of a connonical question from Stack Overflow:

[What is a NullReferenceException, and how do I fix it?](https://stackoverflow.com/q/4660142/76874)

**How should we handle these?**

**Full Disclosure:** I am the mod who put the question referenced below "on-hold" so we can have this discussion. I am perfectly fine with being overruled on that...
