There are quite a few questions one could ask about vim that can be legitimately answered with "yes, here's a link to a plugin that does exactly that."

For example:

* [How can I comment code with a command in Vim](https://vi.stackexchange.com/questions/330/how-can-i-comment-code-with-a-command-in-vim)
* [Applying settings to a directory tree only](https://vi.stackexchange.com/questions/77/is-there-a-way-to-use-different-settings-for-different-projects)
* [How to get intelligent C++ auto-completion](https://vi.stackexchange.com/questions/82/how-to-get-intelligent-c-auto-completion)
* [Can I use some file-tree selector which exists on graphical IDEs?](https://vi.stackexchange.com/questions/16/can-i-use-some-file-tree-selector-which-exists-on-graphical-ides)

How should we evaluate answers that just link a plugin that solves the problem? Should that be considered acceptable, or is it the equivalent of a link-only answer? Or does it depend (and if so, on what)?
