OP, did you honestly not know how expensive it was, as well as a few of these other points in the article? I would be shocked if that's the case. Most of the items in the post are pretty well-known things about the San Fran area. More or less, the title is a bit of link bait, and I doubt most of you don't already know these things about San Fran (or the bay area, for that matter).
Some days I'm sad I moved away (Denver), other days I'm happy to own a home for a lower payment than my rent in the Bay Area.
