I'm saying this from experience. When I posted my question about OP and ED ratings, I couldn't find an appropriate tag by searching "rating", "site" and "list". I didn't even think to look for resources.
Here's the tag's current excerpt:
For questions to help users find useful and valid resources that other community members may use on a variety of subjects related to the topic of the site.
Even though it has the word "site" in it, it doesn't show up when you write "site" into tag section.
