parallax scrolling does not work well on touch devices. People will need to disable it via feature detection or provide a mobile specific version of the site. Usually disabling it should be fine as long as your site does not depend on parallax scrolling to work.
Congrats to bitbucket. Love it cause of the free private repos. However whenever I see bitbucket I remember this spooning video made by them http://www.youtube.com/watch?v=dYBjVTMUQY0
I'm scrapping player data (achievements, ladders, history, etc) directly from Blizzard. As for units/buildings information I had to update them myself right now which is a bit of a pain.
Last for rankings, I'm taking data from sc2ranks.
Yeah there might be some issues with it if it became very popular. However there are already so many StarCraft apps in the app store that I thought maybe Blizzard is okay with it.
Otherwise this is really great!
