Yes, I know. nginx is pretty awesome and I use it a lot in various servers. jsonip started as a node.js side-project for me a few years ago, and its scaled beautifully as traffic has grown. Its my preferred server environment these days, and I prefer to see how far it can be pushed. So far, I've yet to hit the limit on what it can do for this kind of high-traffic application.

In the future, if it started capping out, I'd look at alternatives. But I'm not there yet, and I like to continue experimenting with node. =)
