Nothing would make me happier or prouder than my home town hosting the Olympics, but, as I believe has been covered many times in this forum, weather in San Francisco proper during the summer would not be ideal. Too cold and windy for most outdoor events.
However, I do think there's potential in the current site of the Oakland Coliseum complex, where the Raiders/A's share a stadium, and the adjacent indoor arena where the Warriors will play for a few more years until moving back to S.F.
With the A's are interested in moving to San Jose/Fremont further south, and the stadium needing a serious upgrade for the Raiders to stay (not that I care), and the general area in need of some revitalization, it could be a suitable locale for the Olympic Stadium (if perhaps a bit too small to serve as a bigger Olympic complex), built to be converted to a football-only venue (or baseball as well, if the A's stay) following the Games.
It's already accessible by public transportation (BART) and a freeway (I-880). It's not a terribly nice area, but neither was the area around Turner Field, from what I understand. Stratford (London), wasn't exactly on par with the nicer parts of London, come to think of it.
Best of all, the marathons could be run from the north side of the Golden Gate Bridge, into S.F. along the waterfront, over the Bay Bridge, and finish at the Olympic Stadium. Yes, I know. Such a course would create major traffic headaches, but one can dream...
