I voted ISTP. Not only are their one-liners hilarious most of the time, they often put things into perspective with subtle insight. Don't get me wrong, I love speculative posts other Ti users make, but if I have to decide on one-- it's gotta be the sensing Ti-dom. I really appreciate the ability to process so much of that background noise & sum it all up in a few short phrases that can easily fit in overhead compartments.

Maybe it is related more to the instinctual variant than the MBTI type?
Judging the quality of a post will always be subjective. I'm selecting Sp/Sx by defining well written posts as posts which are thorough, that are not looking to make a point (but simply trying to communicate their points of views) and not trying to sound smart. Add MBTI to the equation I'll say it's INFJ Sp/Sx.
