Really, it surprises you? A website tailored to typically well-educated people with a strong interest in science and technology who all speak or can communicate in English and put some kind of value in online discussion.

That’s already 0.00001% of the population, of course we’re a bubble.

The question is: is HN ahead of the curve with distaste toward FB, or an anomaly? There’s another thread on this post discussing just that.

Not necessarily ahead of curve, most normal people don't care about the feed algorithm. They are happy to see what their friends and family are doing.

The problem here is that MAU statistic is extremely suspect.

I agree. but the deviation is not that huge.
