FamFamFam Silk Icon Sprite
Now, the most popular icon set in the world gets HTTP optimized.
Because of this Facebook image and because we shouldn't have to make the user load each and every icon. A single big download once is often faster than several small ones.
ruby script/plugin install git://github.com/JackDanger/silk_icon_sprite.git
Should I fork this and improve it?
Yes, right now.
Should I host the image on my CDN for the world to enjoy?
Yes, please do that so the world can use this wonderful icon set even more easily. Let me know where you host it and I'd be happy to use your url as the official one.
