I'm a proud luddite among the tech-literate and don't have a Twitter account. Thus, the best way to reach me is via email at firstname.lastname@example.org. De-obfuscating the aforementioned address is left as an exercise to the reader.
Developers might also be interested in visiting dpmccabe on GitHub. I'm not the most creative person when it comes to inventing usernames (or website names for that matter).
