I've noticed that pages where I have marked with +1 have "You +1'd this" in Google search results.
However, it doesn't seem to affect the order of results, or there may be very small differences I can't see or notice.
How do I get pages marked +1 on top of other search results?
I was thinking of using it like a "read it later" or similar service. Like when I mark web pages "read it later", but never read them. If +1 marked pages appear on top of search result, it may be the time to read them.
