I have the Slush Pool website bookmarked on my iPad and iPhone to check up on my status, but don't like the web page screen shot that it uses.
Request to Slush: could you add the apple-touch-icon meta tag to your site to give the bookmark a better look? You already have the bitcoin icon in a nice large size and in PNG format, so the only thing needed would be to add the meta tag to the websites
section. Here is the code, using the bitcoin logo URL.
