If you read only two, then follow Martin Weller and Doug Belshaw.
No time now, but I want to go back and re-blog Doug, even take some tips on knocking my own e-learning blog into shape. This is like going into a niche bookstore that ONLY promotes stuff on education and e-learnig.
Invaluable across the Masters in Open and Distance Education (MAODE)
The book is good too.
