Finally. The philosopher in me always wants to work up from first principles, so I felt like I had a lot of work to do before I could write this. I’ve written a bit about some ways to think about social media and online spaces, what engagement means to me, and what I look for in improving communication. Now, and only now (Thanks Kant, you big jerk), do I feel comfortable talking a bit about the value that social media has to higher education for teaching, research, outreach, and mentorship. This is just an overview, there’s a lot to say on the subject, and I hope to do more than scratch the surface, and share what I do every day, when I’m not creating pages, sitting in meetings, and taking care of assorted administrivia.
