I'm fairly new to Twitter but have been coding in Python for quite some time. I've been trying to build up my list of people that I follow and who follow me. While I was looking around I whipped up a list of some Python developers who have a lot of really interesting/helpful/insightful things to say about Python and things in general.
The following 15 people made the short list this time; there are way more Python developers extant than I have time/space to write about them so let this get you started. I apologize in advance for those who I left out.
