For a long time, "meta-tags" have been discouraged on Stack Exchange.
Today I ran into the tag learning, which I think is one of these not-useful tags. Questions about "learning" don't seem to be much of a meaningful group where someone might have expertise. It's not entirely a meta tag because teaching English to learners is definitely somewhat of a skill of its own ... but I feel like people wanting answers that are more holistically oriented towards "learning" should be asking on English Language Learners or Language Learning rather than here. So to the extent that it's not a meta-tag, it seems to be a broad attitude-based tag that has an unfortunate (in my opinion) overlap with other sites. (I don't think all overlap is a bad thing, but this kind of overlap seems pointless.)
The tag has 81 questions and 5 followers, which is not tiny but not huge either. The highest-upvoted question with this tag, What is meant by “steep learning curve”? (current score 26), seems to have been tagged by accident just because it is about the word "learning".
I propose eliminating the tag "learning".
