for me it is about page loading - pretty much straightforward successful and predictable on HN and slow and/or heavy, jerking current position/scroll around and full of whatever else surprises the page of the source. I want to know what it is about immediately, i.e. basically it is an issue of instant gratification for me :) If information on the HN comments page isn't enough (which is rare), or the source is really vouched/confirmed to be interesting by itself - then i take the bullet.
