Wow, I had no idea this site existed, but I love the idea. I don't regularly use a Windows machine, but I'd love to see something for Linux users in the future.
Even for us Debian/Ubuntu users, I'd like something like:
[ ] Build LAMP server
[ ] Build LEMP server
[ ] Build RoR server
And it give you the script/apt-get commands to install all of the required packages, similar to how Linode install scripts work.Regardless, this is awesome. Those download software sites are a relic of the early web that need to die.
