Really? If you mean 'your version control and build systems can handle more load than his blog,' perhaps you are correct. But the expression 'scale' refers to the rate at which increases in load places increased demand on resources. Unless you have a very specialized infrastructure for VCS and builds, it probably doesn't scale at a lower rate than his blog infrastructure scales.
Do you know what his blog infrastructure is? Over 3 hours later its still not working. Git is decentralized and can and does scale. Builds can be spread across multiple machines on EC2.
From 2003 until a few months ago, I hosted my website off of a Pentium 2 in my apartment. Behind slow DSL, no less.
Once my blog posts started reaching hacker news I thought "Oh, I'll just move site out of the apartment and into the cloud!" and bought an account at prgmr.com (which I highly recommend, by the way).
However, I serve WordPress via Apache on a 256 MB VM, which clearly thrashes under load.
Tonight I will purchase an upgrade to 512 MB of RAM and play with nginx.
I'm sorry for the inconvenience.
p.s. I do have WP-Supercache enabled and a PHP bytecode cache. I _could_ just host at wordpress.com, but I might as well learn nginx while I'm at it...
