Our tagline in the FAQ is as follows:
User Experience - Stack Exchange is for user experience researchers and designers.
I'm wondering if we aren't getting as many Information Architecture and Human Computer Interaction questions because they're only implicitly included in here; and at many places, these are separate job functions, even if our site accepts all of them.
We still get plenty of UI design questions; probably in part because many "UX Design" positions do 80% or more UI design, but research level HCI doesn't quite fall under the umbrella, and Information Architecture has been kept more distinct a job function when it exists, where UI/UX merge for lots of smaller companies.
Would it be worth expanding this line a bit to include Information Architecture and HCI? Should anything else be included? Is this a problem?
