The PledgeBank is an awesome site that gives people the confidence of numbers.
The idea’s simple. Make a pledge, any pledge, conditional on a number of other people joining in.
Pledges can be symmetrical (everyone does the same thing)…
"I will march on the White House in protest at X, if 1,000 people will join me."
"I will paint my car bright yellow, if 200 people in my city will pledge the same."
…or a-symmetrical (you offer more than you ask from others.)
"I will take $100,000 worth of sleeping bags to Pakistani earthquake victims if 5 people will join me to help distribute them…"
"I will host free pizza at 10pm on my street, if a minimum of 30 people pledge to show up."
The reason this is brilliant is that so many people are reluctant to get involved in social change issues because they feel like their one voice won’t do jack. This overcomes that.
