Couldn't make it to Future of Web Apps in Miami? No problem, we've got you covered. Wordpress.com's Matt Mullenweg just left the stage after dropping mad science on what it takes to scale a major league web application.

There's no way we could summarize everything Matt said on the how and why behind scaling Wordpress.com but, here are a few (rough) notes:

• Do the easy things first. For example, before throwing more hardware at your application, try building a proxy wall with Squid.
• Wp-Cache can do quite a bit for mid-scale blogs. (We recommended WP-Cache on The Squadcast in episode 11)
• Really large scale applications can't live without Memcached.
