Another thought on Facebook Like vs Google +1...
When people click a Facebook Like they aren't just supporting a page they like, they are also automatically sharing that with their friends. The idea of sharing it is a big part of their motivation in clicking it.
The +1 lacks that motivation. They aren't sharing the site with anyone, their click just goes off into this vague nethersphere. Where does it go? Nobody knows.
