Contact Ben Horowitz for $20

Neat idea. It does seem like a bit of a publicity stunt - I don't think Ben Horowitz really needs the 20 bucks, but this is a cool use case for bitcoin.

...

It was 5 dollars when he announced it on Twitter. I guess he adjusted it after seeing the response.

It may could encourage people to contact him more by giving them a form of permission:

> To come to our surprising conclusion, Uri ran an experiment: Out of 10 daycare centers across Haifa, they randomly chose six and introduced a small fine for parents who showed up more than 10 minutes late in each of them. In day cares where the fine was introduced, parents immediately started showing up late, with tardiness levels eventually leveling out at about twice the pre-fine level. That is, introducing a fine caused twice as many parents to show up late. What about the remaining four day care centers that remained fine-free? Tardiness didn’t change at all

I missed that. Well still, I don't see this as something he will keep up. I still think it's mostly a temporary publicity stunt.
