It's a carbon copy of this template: http://themes.getbootstrap.com/products/marketing Even the pricing area and the footer text are 100% just a copy.

This is why I love HN. If it is not authentic, you quickly get found out. OP, why didn't you at least edit the page and make it your own?

This isn't specific to HN, you get the same thing on various subreddits on reddit (e.g. /r/science and /r/technology), and probably the same thing on any technically-oriented community forum that discusses new or any tech. HN is great but let's not start a circlejerk around a common feature of any strong community.
