A lot of people here seem to be suggesting that we should simply ask users to click.
Maybe that explains why the Facebook like has worked so well? The default Facebook "like" button, while it doesn't straight up ask you to click it, the mere fact that it says "like" sort of suggests to people to tell the world whether or not they liked what they just saw. It seems natural.
This vague +1 thing does not. +1 what? +1 dollars? Am I donating money? It's not clear.
The other thing the Facebook like button does that this doesn't, is that it clearly identifies itself as being from Facebook. Most of them have the little "f" Facebook logo next to them. People trust facebook so they feel good about clicking it.
People also trust Google, but the +1 does not identify itself as being from Google AT ALL. Nobody knows where it's from, so they don't trust it and they don't click it. If they knew it was from Google, they might click.
