The way people look at "Like" is it's a piece of content or such that a person "Likes" however it's a good pointer using that term out of the dictionary.
Something like +Ok, i don't think some people will grasp that too quickly.

If you used something like "Agreed" "Agree" or something in that nature it lets publishers know that it's something that makes sense even though they may not like it, they still do agree to that content.
Or maybe "I Approve" see more or something like that lol
