I'm currently reading Small is the New Big by Seth Godin. His bio describes him as an author, an entrepreneur and an agent of change. He is also a well known blogger. The book is in fact a compilation of some of his blog posts.
On my way home I read a great post about feedback. It is entitled How to Give Feedback. In it, he argues that when people are asking for your feedback, they are not asking for your opinion, but for your analysis. You think this sounds interesting? I invite you to read more. How to Give Feedback.
