Please merge tag ux (13 questions) into user-experience (68), and make them synonyms.
Neither of the tags has wiki, but questions in both are about user experience (UX).
Preference for master tag is because it has much more questions.
Just so there's an answer...I did this.
And, for the record, even if ux had more questions, I'd make the master user-experience since it's more descriptive.
