I think demonstrations are great, if you use them to get names, addresses and emails and build a network of people who are dissatisfied with the status quo. (According to Congressional approval ratings, that would be just about everybody, but everybody keeps re-electing the same clowns anyway--not that new clowns would behave differently). But, they are not going to change a single vote in Congress. Neither are internet petitions or contacts to Reps.
Then again, the NSA will monitor your emails. Maybe this is really why they are so anxious to privatize the post office. Mass mailings are already fairly expensive. Just imagine how expensive they will be when the Post Office is finally done in. And the 4th amendment doesn't apply to private companies.
