A note about social networks and professionalism:
Please don't contact me on Facebook for anything work-related. I know some reporters have different approaches to this, and we're all trying to navigate how technology blurs the boundaries between personal and professional. But I don't use Facebook for work. If we have an ongoing professional relationship, LinkedIn is a good place to find me. I read email that isn't spam and respond when appropriate.
In short: use common sense. Thanks.
