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
- Applying settings to a directory tree only
- How to get intelligent C++ auto-completion
- 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)?
