Speculation: You were being downvoted because software types often express ideas that can be summed up as business is easy and the people doing the business aspects aren't important. They seem to think that everyone and anyone can do it and, when they hear success stories as examples, it reinforces those ideas.
A good example is some of the comments that software folks make about the sales department.
They are different skillsets and people have varied abilities in each. The business aspect is not actually easy. It is also not always done well. The software end isn't always done well, either.
My guess would be that is why you were being downvoted. I notice a number of votes are emotional in nature. They aren't based on logic. I see some that are most easily explained as, "I don't want to know." The comment is factual, not confrontational, and topical. The vote is still negative.
Meh... I don't mind it when it happens to me. I have karma to spare and don't actually make comments for the points. I say what I feel needs to be said and try to stick mostly within the guidelines. (I do meander off topic sometimes.)
But, no... I don't comment for the points. I comment for the replies and thoughts. They are usually quite brilliant and insightful.
