Every now and then, someone posts a short answer along the lines of
Use module [X][1].
[1]: [appropriate link]
I've done so myself at times. These answers are sometimes flagged as low quality, probably due to how short they are. In a recent case, someone has commented that "link only answers" can become invalid if the linked page changes. This comment also has an up vote. While that can be true, in the case of modules, the answer is sometimes literally just "Use this module".
For the fictional question "How do I add weights to flags?" and the equally fictional module "Flag weights", the "best" answer is probably just to inform the OP that there is a module that performs the exact and narrow task that is being asked for.
It's obviously different for some of the more complex modules, say Views, which isn't just "install it and it works" because they require significant configuration.
While I understand that the flags are not going to change, I'm wondering if we really should consider these simple answers "low quality" when reviewing them?
