I agree with there being a huge problem of it becoming vastly too easy to do. And there does seem to be a huge discrepancy on the internet, between what people feel is important enough to cause such a ruckus and what's not worthy. Ranging from real human rights issues to he said she said pointless crap. Perhaps it would mean more if you had to sit there hitting the refresh button in unison with a group, instead of just running a script to do it for you. You no longer need to be a charismatic leader to rally the troops, just infect computers with a botnet. Such singular power executed through such forceful means does seem more like tyranny than justice.
I wonder what a better equivalent to such traditional means of the public showing disapproval would be online?
