These days, someone launches a new open source product with an insanely well designed web presence. This open source project has a better visual design than I could make in two months: http://www.serfdom.io (along with the related http://www.consul.io).

Erlang is still stuck in "my first bootstrap page" mode of marketing (which is an improvement over the old version which was My 12 Year Old Neighbor's First Webpage mode).

Erlang is designed to appeal to people who already like Erlang. It doesn't get all the new programmer hyperfad attention of things like Go, but people who know how to use Erlang properly do amazing things more reliably in shorter timeframes than other programmers even know how to think about.
