On: Series E Terms for Twitter

[fizx]

"Realtime" is amazing and new, when it's in conjunction with web-scale data. Remember when Google used to take weeks to update its index?

> The technology twitter is simple, anyone could build it. You could likely run twitter on 10 servers max.

I'm not sure whether you're being disingenuous or naive.

I'm just stating a fact :/

It's a simple message passing service. It's pretty much as complex as a router that supports multicast UDP. eg not very.

Multicast UDP is so easy that it has never successfully been deployed at Internet scale.

Building a router that supports multicast UDP is simple. Getting THE INTERNET to all simultaneously upgrade is the hard bit.

[tptacek → axod]

Maintaining group-based routing tables for individual pieces of content as opposed to hosts that serve many pieces of content is a hard problem, and no vendor has solved it.

You are naive. It's a dead simple system.
