Every single time I visit some low-rent website which gives the option of downloading an ill-considered, poorly-designed, incomplete, app-based version of itself, a small part of me dies.
Maybe that means one day I'll crumble. Like Randall Munroe explains in the alt text of today's XKCD:
If I click 'no', I've probably given up on everything, so don't bother taking me to the page I was trying to go to. Just drop me on the homepage. Thanks.
Or, better yet, scrap your stupid app and make the mobile version of your website useable. Just a thought. [XKCD]
