This post is about minimizing hypocrisy. Too often we do not pay attention to the things that others have built for us.

Don't we wish that our customers would pay close attention when they are deciding whether to use our products? Of course we do.

It's easy to be stuck in one field and obsessing over the smallest details, but I agree that it's good to branch out and see what obsession is happening in other fields. (In particular, consumer products). Although, remixing those ideas can get messy (see: Skeuomorphism).
