Sorry, but I strongly disagree with you. Reading the cited book (Smart and gets thing done) was an absolute eye opener for me, and for every person that I have recommended it to.
Really, you should read it (unless you were only trolling). It is a very fast read and full of insight.
Also, "tech Q&A site " is a huge mischaracterization of Joel's blog. He has really insightful articles like "Evidence based Scheduling", or the ones about (not) rewriting-code.
Hosting a tech Q&A site doesn't make you the canonical source of how to structure interviews.
The live coding interview style was a toxic and negative contribution to the tech industry as a whole, IMO.
