There are 58 questions that are actually using learning, which puzzles me a bit.
Is the tag even useful? If it says something, it tells me users are asking a question because they are learning English, which seems obvious since the site is English Language Learners. Plus, I don't see any difference between a question asked by the users who are actively learning English (i.e. following an English class), and a question asked by users for which English is a second language.
Can we define the tag in a way that makes it helpful, and not a too generic tag meaning (for example) I am asking the question because I am taking a class to learn English? If it can be used to mean this question is about learning technique as Damkerng T. suggests, what can we put in its tag wiki to make it clear in which cases the tag should be used? Should we rename it?
As noted from J.R., we also have mnemonic. learning should have a different purpose, or mnemonic should be instead used.
