The difficulty of runing a corporate Blog

I was recently tasked with runing a corporate blog, dealing mostly with crisis management and communicatios. This being supposedly a corporate affair, many people are supposed to contribute articles and posts, but so far of those I have only received one, and the rest have been written by me, and that has really been complicated, since I am running out of ideas and topics to write about without giving away too much proprietary information, or teaching people how to do waht we sell... Oh well, I truly hope this works in the end, and if you are intereste in crisis management and can read Spanish, visit my corporate blog
