Avoid meta-tags
Do not use meta-tags in questions. Here are some tips to help you determine whether a tag is a meta-tag:

• If the tag can't work as the only tag on a question, it's probably a meta-tag. Every tag you use should be able to work, more or less, as the only tag on a question. Meta-tags, like [beginner], [subjective], and [best-practices], are not helpful by themselves – they do not communicate anything about the content of the question.
• If the tag commonly means different things to different people, it's probably a meta-tag. For example, the meaning of the tag [subjective] is, itself, subjective; the same is true for tags like [best-practices] and [beginner]. Best practices to whom? Beginner by what criteria? Use only tags that have a broadly accepted, objective definition.

Common meta tags on Web Applications attempt to describe some aspect of what the person is trying to do. For example, someone might use [delete] when they're asking a question about deleting an account or a message, or [subscribe] when they are asking a question about subscribing to a mailing list. Tags help experts find questions they can answer. No one is an expert on "subscribing", although one might be an expert on google-groups.

Use this tag for questions about tags that appear to be meta-tags.
