We can always use some great proxies! How often do you go back and review/update the sites? We all know that many fall by the waistside, some faster than others. Thanks for making the site though, I will bookmark it for sure!
I submitted a site today.. Maybe you can add another field / icon etc to show if a proxy supports SSL or not. ?
I would also do something different with the headings (just above the proxy list entries - not the ones at the very top of the page) that link to the sections, to give them a bit more emphasis and contrast from the text below them, either bolded or different font , use an image logo etc.
