Yes. It's somewhat rational. The city keeps you more in touch with urban culture, the valley gives you fewer distractions. The talent pool is somewhat polarized, with more graphic designers & marketers in the city and more hackers in the valley, so depending on your hiring needs it may make sense to prefer one or the other. It's a shame the commute between them sucks so much.
