Will someone please define the ux tag? It's not self explanatory.
(((Hmmm, looks like I need to add an extra sentence to allow the question to be posted. Let's see if this is enough.)))
The problem with "ux" is that very few people would think to type it when trying to tag a relevant question. To help with that, I created a "userexperience" synonym. Although it's long, it will cause the "ux" tag to be raised as a suggestion whenever anybody starts typing a tag beginning with "us...". Try it!
Click on the Tags link under the Geographic Information Systems meta header line, then search on ux which reveals "about how a person feels about using a product, system or service." That is all I could find ... but I have no clue if that is good or bad (aka uch or yuck or equivalent gutteral expression)
