Marc Eisenstadt, chief scientist at the Open University's Knowledge Media Institute, is joining us here at Get Real for a stint as guest blogger. Marc's own blog is My Dog ("no, it's not about dogs"), and his interests are certain to amuse and enlighten. I interviewed Mark last week using KMi's Flashmeeting technology.

I want to thank Carl Tyler, from Instant Technologies, who was our recent guest blogger. It seems I caught Carl at an incredibly busy time, but even though he only contributed a few entries, I forgive him, and will certainly invite him back again. I also will be getting a demo of various new stuff he is building, which promises to be fun.
