Is there some way to lower the amount of RAM that's used? I like the speed and all, but it isn't exactly friendly with resources.
Free RAM is wasted RAM. RAM is there to be used. OS X will use as much RAM as possible. That's a Good Thing™.Next question is why it's like that. I don't get it.
I believe the idea is to use memory if available to cache pages for faster access. As long as the system still has memory available, this is not a problem.

You don't need to worry about freeing up precious RAM in order to anticipate launching more apps in the future. OS X is well aware that you might do this, and is prepared for it.
If you're running "SafariForWebkitDevelopment" in 10.8.4, then you're a developer running a test environment, so that software is probably not optimized for efficient use of resources.
So ... the high use of RAM is -why- it's so fast? Not complaining, just making sure I'm understanding you right.
The idea is the cache saves pages you visited in memory, so if you go back to that page it will load faster since the page is cached locally and almost nothing needs to be redownloaded from the Internet.
You can see it yourself if you clear the cache then visit a page twice. The second time will be faster due to the cache.
Ok but then why does safari reload tabs or pages when you swipe to go back, shouldnt those be in the cache ready for viewing, a la Chrome? I'm not trying to argue against your point. In theory it sounds good.
