But Github is already doing what 37signals is aiming for and that is being a company focused on a single product. I'd think they want to maintain that.
They actually sold Gauges to Fastest Forward a couple months ago. Hopefully the new owners will give it some much-needed love; it's pretty, but... let's say unnecessarily minimalist. (If there's a way to get it to give me all the referers in a time period other than day-by-day, for instance, I still haven't figured it out.)
