Scoble writes something—6,800 writes are kicked off, 1 for each follower. Michael Arrington replies—another 6,600 writes. Jason Calacanis jumps in—another 6,500 writes. Beyond the 19,900 writes, there’s a lot of additional overhead too. You have to hit a DB to figure out who the 19,900 followers are. [...] And here’s the kicker: that giant processing and delivery effort—possibly a combined 100K disk IOs—was caused by 3 users, each just sending one, tiny, 140 char message. How innocent it all seemed.

In the big picture, Twitter did exactly the right thing. They had a good idea and they buckled down and focused on delivering something as cool as possible as fast as possible, and it’s really hard, in early 2007, to beat Rails for that. When all of a sudden there were a few tens of thousands of people using it, then they went to work on the scaling.
