Adam DuVander Hi! I'm Developer Communications Director for SendGrid and former Executive Editor of ProgrammableWeb. I currently serve as a Contributing Editor. If you have API news, or are interested in writing for ProgrammableWeb, please contact Though I'm a fan of anything API-related, my particular interest is in mapping. I've published a how-to book, Map Scripting 101, to get anyone started making maps on websites. In a not-so-distant past life I wrote for Wired and Webmonkey.
