I honestly can't say that the Tenderloin is really coming around that much. I don't live in the city anymore, so maybe it has changed since I left, but I honestly would have never guessed Twitter worked in that building if I hadn't known so myself. The area is still the same: dirty, lots of homeless, run-down establishments, etc. Now there is just new construction going on.

I think we are going to have to wait a year or two until these towers are finished before we know how receptive the tech workers will be to living in such an area, and whether or not their presence will really spark gentrification in an area that has resisted it thus far.
