I thought I saw someone here shrugging off the risk of MitM attacks. Be 
careful. An awful lot of users connect via wifi, and, as flawed as the 
certificate system is, it makes it hard for random evil hotspots to 
pretend to be your bank or your e-mail. If we were back at plain http 
these attacks would be a big problem. The system does work…to the extent 
it works.

A different point: If bigish nation-state wants to MitM the connection 
to my bank, the certificate system is not the hard part. Just get a bent 
CA to issue the fake certificate they need. But mostly this isn't a big 
problem, nation-states mostly can't be bothered and have better options.
