LEADING THE DAY:Twitter told the city of San Francisco that it will stay if it can get a tax break for new hires. San Francisco levies a 1.5 percent tax on payroll.

The San Francisco Examiner reports that Twitter expressed its intent in a letter to the city’s board of supervisors, saying, “Twitter is committed to signing a lease that will keep the company in San Francisco for six years and likely for a subsequent 10 year renewal term.” Without a tax break, Twitter said that it cannot justify the cost of staying in the city and will move south to Brisbane, Calif., where it estimates it could save $30 million. Even with a tax break, according to Business Insider, the city estimates Twitter will pay $35 million in city payroll taxes over the next six years.

Judge says Sony can look at hacker’s PayPal history:A judge has granted Sony the right to look into George Hotz’s PayPal account records, according to Ars Techinca. Sony claims Hotz received donations from people in northern California to fund his hack, adding evidence to back Sony’s claim that the case should be tried there. Hotz and others were served restraining orders from Sony earlier this year after releasing a hack for the PS3 intended to allow users to install other operating systems on their consoles. Sony said this hack enabled players to play pirated games. Two weeks ago, Magistrate Joseph Spero granted Sony the right to acquire the IP addresses of anyone who visited Hotz’s site .
