WordPress.com use Amazon S3 to store images (presumably to save having to create a massive scalable redundant filesystem themselves) but the images are served via a load balanced memcached / varnishd caching system that they control.

    &lt;p&gt;&lt;small&gt;&lt;/small&gt;Via &lt;a href="http://barry.wordpress.com/2007/11/01/static-hostname-hashing-in-pound/"&gt;Static hostname hashing in Pound&lt;/a&gt;&lt;/small&gt;&lt;/p&gt;

WordPress.com has switched from Pound to nginx for load balancing, resulting in a significant drop in CPU usage. I’ve been using nginx on my little VPS for over a year now with no complaints, nice to know it scales up as well as down.

WordPress.com now supports inline LaTeX. A great example of a feature that will turn a small subset of a user base in to life-long fans.
