So basically, the plan is just to complain to each other about how much it sucks?
How about writing to your congressperson on that day? How about sending lots of PGP (or whatever the state of the art is today) encrypted emails? How about putting a long string of trigger words in every email you send that day? How about sending letters of complaint to companies which are complicit with monitoring? How about writing a big fat check to the EFF?
