I've wondered that myself, for quite some time, and refrained from asking it publicly because I knew it would be interpreted as a personal attack. It's not. I'm genuinely curious what this guy's credentials are. To name two other people on HN who write stuff on the web that gets read here: We know what Paul Graham has accomplished, business-wise, and Jacques Mattheij. (And if you don't know up front, it is easy enough to find that out about either of them.) That's why people are interested in what they have to say on their personal sites. That is their credential (in terms of "why should you give a flying fuck about my personal opinions on X topic?").
I've gone to the HN profile and the About page of his blog and anything else I could find for Sebastian and can find no enlightenment as to what he actually does for a living. I can't find that information in spite of spending some time trying, which is one reason I typically do not read his blog posts. Again, it is not intended as a personal attack. If he's for real, this is an opportunity to enlighten us all and self-promote in a positive way. It's only an ugly thing to ask if he is essentially full of hot air.
