That wouldn't be consistent with other Xs on the site. Alhough I do agree that it would be better to skip the trivialities.
Probably. I first looked at the page on a tablet, where the viewport is much smaller and so scanning/skimming is much harder. I later got back to the page on a laptop, and I scrolled past uninteresting parts without any problems.
One thing I think would be good on learnxinyminutes is an ability to link to a specific line. Is it possible and I just missed it?
