I do not think your attitude or position are indicative of the majority of developers. They also require a huge time investment up front by the interviewer. Even if your individual Github profile (or whatever) is organized, comprehensible, and relevant, it doesn't say anything about the vast majority of developers whose profiles are largely scattered, obtuse, and frankly not even representative of their own work.

If you are a recognized leader in a particular field your situation is obviously different, but you can't expect me as a interviewer looking for a web developer making a mostly standard CRUD app to have the time to delve into your personal history and divine your technical expertise without asking you about it.
