There've been some meta-questions about tags for textbook exercises, see this one in particular. We have the tag nielsen-and-chuang for Mike and Ike, and we have a general tag textbook-and-exercises for others. Both seem to be pretty well accepted.
In the last 24 hours I have seen at least two questions lifted closely from Wong's recently published/made free-to-download "Introduction to Classical and Quantum Computing". This makes sense perhaps, because at the end of the book Wong indicates that QCSE might be a good place to ask for more help. Seeing as the book was made available only a month or so ago, perhaps there may be more questions coming.
I, for one, appreciate Wong's shout-out, but does this provide a suggestion that we should have a tag specific to Wong's textbook, much as there is one for Nielsen and Chuang? In my haste I attempted to create a wong-textbook tag, but perhaps that was premature and I should have tried to get a consensus? Thinking about it more, I'm also not keen on the name of the tag that I just created, to be honest.
