As an aside note, I don't like when OP's don't interact with the posts they make. Especially on posts like this it would have really interesting to gain more insight on where he was coming from or if the replies are making sense in his mind.
I'm probably reading too much into this, there are many reasons not to reply, but when I see a popular post that has 0 replies by OP I feel there's dishonesty.
Why not?
(Also look at the community you are replying in... What use is there on quesrioning why people use reddit on the c/reddit, it's like when people say "why are you using 4chan" on r/4chan lol)
