No offense, but there were other ways to word that statement without sounding like a jerk. I understand that probably wasn't your intention, but yes, you could choose better words to use instead of that, in particular the "haha" bit and, my personal favorite, the "you must've been under a rock for a few years" part.
'Haha" set the tone for the whole post, as in joking. But next time, just for you, I'll make sure to convey my message as best as miss pretty princess pony would.
