If you happen to spot me at a conference, try to make sure you're not accidentally talking to Chap Ambrose. This can be especially difficult, as we've impersonated each other in the past.

For quick questions or comments, you can tweet something to @seacreature. However, twitter is a poor conversation format. I'd much prefer it if you write a blog post and then send me a link, or if you catch up with me via Freenode. Just send a message to seacreature in the #mendicant channel.
If you want to talk to me in private, you can email me at gregory.t.brown@gmail.com, but please keep in mind my inbox is very busy and it might take me some time to get back to you. For the most part, I tend to respond to every email I receive within a few days, but occasionally declare email bankruptcy if I fall too far behind.
