I have been going on about this for a while now and this week I am taking my social media story to a conference at the Maastricht School of Management. The conference has the theme: Revolutions in education: New opportunities for development.
My point is that it is getting tough to publish. Even your local society journal wants clean identification of causal effects. The quick reply to such worries are to do better work. I argue that that is necessary, but may not be sufficient. You also need to work on your reputation for doing good work and collaborate with people who already have that reputation. It is at this point that the social web can come to the rescue.
Prof Wim Naude and I will soon launch an online survey about this. Stay tuned for some empirical results.
