There has been a barrage of tag wiki edits by a user today and although they looked good when reviewing them, it made me wonder if it would be a good idea to mention the sources when constructing a tag description or tag wiki?
I must admit beforehand I did not mention my sources when making my first tag descriptions or even wikis, but of late I have been doing this, e.g. when I made the signal-processing tag description.
Would it be good to urge users to add their sources or is this unnecessary? Personally, being a big fan of adding my sources, I would opt to start asking users to do it.
