I want a hate button. I promise that I probably won't abuse it.
"For example, someone uploaded a very enticing photo, sometimes your having a second thought what word would be appropriate to express your opinion about the photo, LIKE button would help.."
Uh. Why don't you just write "I like this picture"? Other than the fact that it sounds totally vapid and boring. Let me think about other things that are totally vapid and boring...oh! Like buttons. Those things.
I'm pressing my hate button right now.
I've been suggesting a +1/-1 Karma function for all site content for fucking ages now but Aesir are too busy drinking mead and banging shield maidens to respond to such a request.
That reminds me. Either one of the mods was fucking with my account, or there's a security vulnerability that hasn't yet been responded to.
