I encourage this. Two observations. One, most companies hiring for these roles (i.e. growing fast) are in the Bay Area. Two, I've seen a material difference in performance between support that meets, in person, with the main office (e.g. management, engineering and sales) once a month or quarter versus those who just join on calls. The number of times a support person's recounting of some random interaction is overheard by someone who makes a decision based on that story is huge.

The big issue is the Bay Area's old timers are attempting to control the gains from this economic activity through their control of its real estate. This, in my opinion, is a national structural problem more than a local one.
