We have a meta question here for an ongoing effort to add tag wikis and usage guidance for tags on the main site which is great and helpful. If we had usage guidance and wikis for ever tag on the main site, that would be wonderful.
However, we have a number of tags on meta with no guidance or wiki (though we probably only need user guidance on meta). I think we could benefit from adding them just for sanity and to help people who are new to meta. Some of the tags are relatively straightforward, but some could use a bit of clarification. Like what exactly is the difference between suggested-edits and editing. If I am asking a question about an edit I suggested should I use both or one or what?
We probably have some tags we don't really need or that could be grouped with others, and we can probably figure that out as we go along, but I think that with the smaller amount of tags on meta, we could probably get usage guidance for most, if not all, of the tags and the site will be a bit better off for it.
