A question about meta tags: Should we use for questions about favorite tags? Or will we simply use for this purpose?
Just to have them in one place, I'll collect here previous messages from this room about this.

I see that Asaf Karagila removed both occurrences of the tag on meta: https://meta.mathoverflow.net/posts/3615/revisions and https://meta.mathoverflow.net/posts/2798/revisions

I planned to ask Federico Poloni what was the intention when he created the tag in this question: Tag warnings on MO. But this is now moot.

It seems that the tag hasn't been used in other questions: http://data.stackexchange.com/meta.mathoverflow/query/787716/posts-which-had-giv‌​en-tag-in-the-past?tagname=interesting-tags

@MartinSleziak Now I see that is one of the default tags, so it's not removed even if it has zero questions.

On this meta there is no such tag, but this topic falls under . At least according to tag-excerpt. (Which was created by me. I think I've copied it from Mathematics Meta.)

A synonym $\to$ might be reasonable. This would be similar to the situation on Meta Stack Exchange. Of course, this would also mean creating the latter tag.
Probably also a synonym $\to$ would make sense - and the later would be used both for questions about favorite questions and favorite tags.
