Mainly because I came across them from reputable sources (usually from others on the list like Smashing Magazine). Additionally, the list is more aimed towards web apps, so your recommendations wouldn't fit (many thanks though).
With all that, if you don't like the list having things I haven't used, why recommend that I add other sites I haven't used? Not being an ass...just curious
Haha good point. I worded that badly, I was adding to the list in general for other HN readers, not saying that you should actually add them to your post.
I would add these to the list, which have been essential to my learning iOS design: http://pttrns.com http://www.teehanlax.com/blog/iphone-4-gui-psd-retina-displa...
