Ah, I think I see... you're saying that Facebook is an overall net negative to society. Even you now acknowledge that it has some uses, but you consider them to be outweighted by its negatives.

Your original comment made out that Facebook has no uses at all. I think you were just trying to really emphasise your point that it's a net benefit overall, but you've ended up saying something totally different. I know that sounds pedantic but it undermines your point because most people will read its literal meaning (like I did) and then just think, oh, this comment is factually incorrect.
