How seriously do you really take security if you let your certificate expire like this? Is g10code.com legitimate?
There's a rival proposal in the House called the Online Protection & ENforcement of Digital Trade Act, or OPEN, which claims to be better than SOPA/PIPA but does similar things in a different way. I suspect it's better to do nothing at all than approve any of these bills, even OPEN, but it's hard to say because OPEN doesn't get as much coverage. It would be nice if OPEN were included in the discussion in the future.
When you don't know what to do, walk fast and look worried.
