My comment was sincere and I stand by it. The article was quite long and I've often seen similar summary comments for such articles here on HN. I think for really in depth articles it helps to have a good overview before commiting time and diving in (something more than an obscure title and the valve.com domain). In this case, I was initially under the impression that it was part of an ARG, a topic I am very interested in.

I should also note that I don't see anything in the guidelines about asking for a summary.
