On the other hand HN users influence is much greater than their numbers because many of them are doing tech support for family and tech advice for friends.

I used to do that a bit in the past, but not even my completely technologically illiterate father asks me anything anymore since he got an iPad.

While he is not the type to install new apps, all my friends are, and never ask me for any advice.

Anecdotal, but I think HN users do not have all the power you think they have.

A tiny fraction of the people writing apps.
