RequestPolicy Continued in FireFox, and perhaps other plugins that control/restrict cross-site requests, asks for permission before redirecting to superdodgysite.com and safeandwonderfulsite.com. It's not a feasible solution for the masses, but I really like the control over browsing that it gives.

For the uninitiated: just add a + to the end of any bitly URL to expose metrics and preview the destination.

Yes, absolutely. And on Twitter with its damn t.co hrefs even though the text is a truncated version of the real thing.
