I don't think either of those two blog posts support your point that randomly picking candidates is as good as actively trying to select for good ones. If none of the candidates applying to YC were good enough to pass some minimal threshold, pg and co. just wouldn't take anyone, unlike the horrible companies in your links who will always take what they think is the top 1%.

I think your last sentence doesn't make sense either. Since when did technical competence not count for anything? Both competence and teamwork are necessary, but neither alone is sufficient.

Point is, randomly picking candidates is a crap idea.
