I once threatened to produce a list of all the hidden (or not-so-hidden) references in the comic. So, always looking for an excuse to avoid actually writing an issue, I've made a start.
It mutated from a simple list of pop-culture borrowings into a set of general notes which may or may not be interesting. So I proudly present...
The Annotated Heroes (Issue #1)
Eventually I'll link it directly to the issues, but for now you'll have to open two browsers side by side or something.
Let me know if you think I've missed anything
