What is the point of discussing MBAs on a website like this? The discussion only ever goes in one direction.
It's not like you're a talented, highly technical software developer, get an MBA, then suddenly forget how to code and only know how to reduce costs by 4% per year. I mean, I don't think I forgot how to code. But I did encounter classmates who boil down businesses to spreadsheets where human beings are merely "capital resources that ate lunch". I can assure you the piece of paper with "MBA" written on it didn't suddenly make them that way.
I'm not going to stop HN from dunking on MBAs but I encourage people to look a little deeper than the person's diploma before judging them.
