We just wanted to thank Jetpack, free WordPress plugin that simplifies managing your sites, for sponsoring the first-ever WordCamp DC!
From their sponsor page:
This single plugin enables Photon (a global CDN for images), uptime monitoring, brute force protection, traffic-boosting tools, single sign on, multiple-site management, and automatic or bulk plugin updates.
Jetpack will have a table presence at the WordCamp and would be happy to answer any questions you have in-person!
