It's really common among our types. There's an xkcd about it, naturally: https://xkcd.com/448/
I do wonder, though. Is it that we're different, or is it just that we have a hobby that can easily keep us awake slightly longer than we should be night on night? Maybe more people have the same innate tendency to slip, but they have structures that keep them more on track, like watching scheduled TV etc. It would be interesting to see if there are more cases of bad sleeping patterns now that on-demand TV is more popular.
Most jobs require physical presence, synchronous communication, or both. IT requires neither despite what some managers say, so this is what sets us apart IMO. We're able to work detached from the rest of the society most of the time. There of course are owls among non-IT people, but they never have the freedom to break their sleep schedule like we do.
