> Why should adding features make an app crumble on a single server?
It's not inherent, but obviously as you have more developers working on more and more things independently, each with different needs, tolerances, and deadlines, it becomes increasingly unreasonable to presume it can all be managed well on a single box.
If they went and added chat, or Twitter-like features, or subreddits, or similar, it might be a lot tougher to keep it all on a single box. It's a lot easier when we're all looking at the same top 30 stories, and pretty limited in how we interact with them and each other.
