In conjunction with this blog site, Global Crossing has defined a fairly open blogging policy for employees to comment publicly about the company. The policy contains most of the core and common policies described at the CorporateBlogging Blog.
I've tended (with a few exceptions) to avoid blogging specifically about my employer here, and this is the first time I've specifically named the company on my blog. That's a tendency I plan to continue here, though I expect to comment from time to time on the company blog site. (You can find a couple comments of mine in the DRM thread on Siegel's blog.) Lest there be any doubt, any opinions I express on this blog (or on the company blog) are my own, and do not necessarily represent those of my employer.
