No I really dislike Paul Graham and I find his writing style to be extremely grating. I wouldn't have said anything but you asked. I guess I'm in the minority on this one and I'm a hater in general.

May I ask, what characteristics/qualities you find so grating in his writing?

Like/dislike of writing style is so subjective, just like musical taste, so I can understand if it's not even possible to verbalize why. Perhaps it's just the "tone".
