For a bit of a more balanced discussion of some of the key points related to SF's housing problems, you might want to read Kim-Mai Cutler's (very long and very good) assessment of the issue:

I don't even want to pick out any quotes because that would be doing it a disservice, but I think it argues successfully that many of the displacement and culture problems surrounding SF today are, at the core, housing issues. And the blame for those problems does not lie solely with tech workers, and the potential solutions are far deeper and more complicated than all of us trying to "not being awful" (though not being awful is a good start).

Another interesting article from Kim-Mai Cutler on the absolutely fascinating Bay Area housing market. In case you missed her last one and the discussion in HN:

One correction is needed: tenancies in common (TICs) ARE NOT a method of avoiding SF rent control rules. It has absolutely no effect on whether or not a particular unit is subject to rent control. It is simply a way that people can share ownership of a multi-unit building - like a coop. On the other hand condo conversion does remove many of the burdens of the SF rent control. That in turn is why the SF government had to essentially outlaw condo conversions. The rules are very complex and constantly changing - educate yourself and then talk to a lawyer.
