Yeah, I thought those code samples would run immediately, in which case maybe the loading would be justified (although surely very easy to avoid). Instead, they're links to a different page that has the same code sample and a link to run the code, meaning I need to press twice to see what the code does when it runs, which isn't a lot but is surely at least one (possibly two) clicks more than necessary.

That said, it's cool seeing some of those samples, because they're honestly not really what I expected. For example, I didn't expect the list subtraction to work at a set operation, so seeing that example gives me a feel for what sort of things I can do with Ruby code.
