Background to Programming Erlang

Now, for a normal blog post that isn't such a big deal (in the sense that publishing an interesting idea usually trumps simply not publishing it, due to never getting it "done") -- but in this case it doesn't reflect very well on the author -- and that reflects negatively on the book (unfairly, I think -- AFAIK Armstrong usually writes well).

Or am I the only one that gets that impression from the post?

At his age a lot of people have switched to doing something else. But he is still programming, exploring, learning, is active in the community.

He would post questions to Erlang mailing lists like "how do I do consistent hashing" or "anyone know of why websockets do this or that", I think that is pretty cool.
