Are all the “+1” comments really necessary?
I see a lot of these and I think it's just noise... If you voted up, why does everyone need to know that you did it? Why brag about it? Especially since a lot of these are just to say "+1 for for this catchy phrase that you used somewhere in your answer and I find it really, really cool, so I am cool too, yaaay".
So if you just want to get to some helpful information, you have to filter through all these unnecessary replies. Considering that on several occasions I've had people remove my "Thank you" at the end of my question because that is considered "noise", I don't see why these types of comments should be out there and "tolerated".
