Question from a newcomer here - why does one <i>have</i> to live in San Francisco?<p>I moved to bay area three weeks ago. I live in Walnut Creek which is the boonies to everyone here in SF but 1) it's affordable, 2) it's safe, and 3) it's quiet.<p>I commute to SF every weekday. I almost always get a seat, pop open my laptop, tether to my phone, and start working. The 45 minute commute usually isn't even noticed.
