Like we see it in Facebook.
Today I was looking a topic and someone posted a thing I realy liked and wanted to say I liked it, but didn't want to "quote", I even, for mistake, (like I'm used to do in facebook) looked out for the like button and reminded I wasen't in face lol.
So, if you put a like button, @njaguar, it would be cool. You "vouch" for something, but don't need to quote it.
