Does this just mean that browser developers are optimizing for the right thing, just not something that benefits you? Tons of people use these sites.

Not really. Browsers try to keep stuff in swap that they probably won't need. Swapping doesn't become a problem until you're almost out of memory as well, and then you might get thrashing. But there's a wide range where CPU optimizations make sense. And such a large fraction of people have SSDs that even swap access can be pretty fast.
