The Kindness of Strangers

I have a few extra computers at home. Thinking they would be good for Tor.
Tor gives you anonymity not encryption, but you can always combine encryption with Tor.
I wish everyone would run a tor node, however very few people do and they can come under very serious bullying by the powers that be.
Also online you can read accounts of how the government intimidates people who run Tor nodes. They ask you questions, they show up at your place of work and ask questions, etc.
Nothing you're doing is illegal, this is just them using their power of intimidation.
If a lot of people ran Tor, the game would be over, but because so few do, intimidation still works, sort of.
It is worth noting that there are also potential risks: http://news.ycombinator.com/item?id=526140
Also, asking a stranger to "watch over your stuff" is unfair. You are burdening him with the responsibility of your stuff while their is nothing in return for him.
Everyone always acts out of self interest.
