How can sweep picking itself bore people? Its just a technique!
It is the same as saying "I don't like arpeggios", which is rather odd, and I think that 'not liking' sweep picking is equally odd... would one enjoy it if the same notes were played with string skipping or some other technique?
If you were to play the left hand part of a great deal piano music written in the 19th Century (which, imo, is some of the most amazing music ever) on a guitar, you'd have ridiculous amounts of sweep picking.
Its just a comment which has confused me for a while.
