any functionality for a "Thanks" or "Like" button (i.e. Facebook)?

OK, perfect example… this made me chuckle.

But if I stumble into a thread that’s been going on and on for days on end, and I notice that you posted this ‘last Thursday’, I’m not going to click “post” “quote MsWhatsit” {brianh333} hey, I have nothing relevant to contribute, just wanted to give you a ‘shout-out’ because I found this post (from 5 days ago) funny / informative".

I find myself thinking that over, and over, and over again. It’d be kind of cool to just be able to click a button that says “I read this, and it made me chuckle”.

I’m not bitching at all - this just came to mind, and thought I’d get you guys’ opinion on it (and I think you guys have answered my question).

Thanks -
