Thanks for this. I had read Derek's post and was uncomfortable with it, and you have articulated the downsides well.

I think blog post appeals to a part of us which wants to be very trusting and open. I actually had a flashing thought of open sourcing our code (which we have been growing for years) but better sense prevailed soon. Of course there are things which we won't want the competitors to know etc.

Although as other commenters have said and I agree, that Derek probably didn't want it to be a blanket prescription. But still it had a pop feel good sense to it. And well thought out 'reality check' kind of response was needed.
