So you think that HN being off for a few hours will make headlines in the worlds newspapers and on the main TV channels? Maybe as an "some tech websites were also offline [and nothing important was lost]" or maybe even (given the quality of some press) "other illegal hacking sites were down in protest against the bill".

I don't have a representative in congress but nonetheless expect congress is already pushing a similar law for my country.

I find the idea lacks any force as a demonstration.
