I don’t have time to write anything today, but here’s three posts from the blog of Hans Gilde that I think everyone must read: one, two and three.
In fact this line of thinking seems to be very productive for me and is producing many more posts. In part it was inspired by your comment on one of my old posts. In that comment, you mentioned about difference in requirements between two types of EP. That difference seems to be as important you had mentioned, so thanks for suggesting it.
Nice to hear that I could provide some inspiration. Keep on writing, I read these with much interest!
