The branding seems slightly off, unless the programming is going to be modified somehow (although, the station has claimed no change). A listener tuning to a station called "LAist" is likely to expect to hear something about LA. But the on-air schedule is filled with largely the standard NPR lineup.
The blog/news site is all local (and very well-done), the radio station is mostly national content. There's a mismatch between the station and its now parent brand.
I think there's not so much concern about the radio brand as trying to tie it all together in a digital world...possibly even looking ahead to where an OTA signal is irrelevant and it's LAist and the app that also brings you NPR programming and news via what we know as KPCC that are the primary ways people connect with their product(s).
