It's attitudes like this that make HN comments so dismal. Ugh.
This is an interesting tool, developed by a group of people doing interesting things, and it's been shared with the world for others to use and/or improve on.
While I'm personally not an Erlang developer, I'm grateful for others who create interesting solutions to their scaling problems. Plus, we utilize Erlang extensively at Whoosh Traffic -- anything that can inspire our developers is always welcome.
