While SFist will bring you election 2010 updates as soon as the numbers start rolling in, you can also keep track online. Behold: California state results page is a good option; here's the link for San Francisco's results. You can also watch live coverage on SFGTV on cable channel 26.
Other sites (SF Appeal, Bay Citizen, East Bay Express, SFGate, etc.) will have continuing coverage as well. Also, get out there and vote!
