I spent 2 years at twitter long ago and now have a little enterprise PaaS organization of about 40 employees, so I'm going to be honest with you: I would never hire someone with Twitter or Facebook on their resume. Ever.
Sorry if that sounds harsh, but to the average person outside of silicon valley, you are seen as a liability and I guarantee your team would resent you anyway. Even if you're one of the few good ones, I can't overstate how poorly Twitter and FB employees are viewed out here in the real world (though I'm sure you're probably getting a pretty good idea by reading the comments on this board). : @1fqd+1juXXuIp
Unfortunately, I think this is the bitter truth.
