larger, more broadly used websites?
I'm a designer/developer. I've launched several small web apps, for myself and for friends. But they have all been the type of sites that just a few people might visit on a given day, and almost never concurrently.
I want to start coding bigger, better things, with many more users. What do I need to learn to do this, if anything? (I typically employ HTML/CSS, PHP/MYSQL, and jQuery. And I just have a $10/month dreamhost account.)
