It would appear you have a non-trivial "company" parse problem, based on eyeballing the "First Time Companies" section. I do appreciate the problem of trying to do semantic analysis on HN comment text, but several of them follow the "X@Y" nomenclature and a few others are "X-Y" so it doesn't seem to be insurmountable to try and fix
This is just a first iteration of a quick prototype to gauge public interest in the idea. It just looks for the "|" separator in the comment title, which is something that majority of posters enforce.
