If you completely remodeled a kitchen around a chest fridge it might not be too terribly inconvenient. But the major blocker is that virtually every kitchen is designed with a perfect spot for a tall, relatively shallow fridge.

Same reason you posted that comment: it's sometimes interesting to discuss a thing even if you dislike the thing.

The bit about aggregation is interesting, but it's not clear to me what the performance characteristics will be for very popular accounts. Presumably Justin Beiber's repo cannot be expected to handle 100 million WebSocket connections, all of which push out a message the instant he posts something. Is it vital to have more centralized hosts which can implement the sort of hybrid push vs. pull models that Twitter famously needed to implement?
