Wikistrat appears to be something new - a massively multiple online consultancy. By registering as a subject matter expert and flagging yourself as available you become part of an Internet-wide virtual consultancy. Consulting as part of Wikistrat is realtime and interactive, it's not just answering e-mails from colleagues across the pond. They are now accepting signups to become part of their consultancy staff. More's the point, you earn royalties when your work is accessed and used by clients, so this isn't pro-bono work, you can make a little on the side. To sign up you have to provide a CV as well as a writing sample.
