chuckling @SXSW Registration phone field: "Please do not include country codes" what do non-US folks put? #ux Perhaps 867-5309. I'm putting 415-555-1212 because no indication is given as to how the number will get used, it's a required field, and it's clearly not important enough to be required since they don't care about phone numbers for non-US folks. required-field + US-only-assumption + no-explanation = you get noise.
