Maybe there's a market for a URL-shortening service that doesn't auto-redirect. Instead it pops up an alert giving the real target and asks if you want to go there.
It wouldn't help the gullible and/or stupid, who'd say "Yeah, of course I want to go to fakebank.com" or those who automatically click through warnings. But for some of us it would be useful. It might even be a way for goo.gl to keep going.
