Seattle has had a better response than San Francisco's: http://www.citylab.com/housing/2013/10/san-francisco-exodus/... ("Over the past two decades, San Francisco has produced an average of 1,500 new housing units per year. Compare this with Seattle (another 19th century industrial city that now has a tech economy), which has produced about 3,000 units per year over the same time period (and remember it's starting from a smaller overall population base)"), but it is still subject to many of the dysfunctional political-economic-legal beliefs described in The Rent Is Too Damn High: http://www.amazon.com/dp/B0078XGJXO.

It's worth noting too that Seattle and Washington don't have income taxes, which can be a substantial issue for many tech workers.
