For EC2 security groups you have to open access to both the correct ports and protocols. Ports are a concept at layer 4 of the OSI model, while ping, or more correctly 'ICMP Echo Request', is lower down the TCP/IP stack at layer 3. So when configuring the security group, look for the option to choose Protocols, then enable ICMP :)

Thanks. This is exactly the kind of stuff that I could learn from said blog post, and why I think "EC2 == VPS" is false.
The documentation I was following made no mention of this at all.
