Any tips for living cheaply in SF?
wannabetechgeek: Sure you can do it. From 2002-2004, I lived on about that much per month, but it wasn't easy.-Rent was under $500 - you can still get these prices.  Sublet a room in a house with some other young people.  
- Electricity/internet bill - $35.  
- Cell phone - $50.  
- Bring down your bicycle and bike for transport - Free
- If you cook every day, and eat mostly vegetarian and rice - not just MSG-infused ramen - you can live on $5 a day - that's $150 for the month.  
- Give yourself $250 for very infrequent meals out, beers, or BART/Caltrain trips - and surprises.I'm guessing most of the people who said you can't do it for $1000 never tried.  If you have to, you make it work.Summer's a great time to live in SF for cheap - lots of free outdoor activities.  2 months isn't that long to tough it out.  Come back again and enjoy the great city when you hit it big :)
