Just a question, I don't use Basecamp or similar products-- does Basecamp have competitors who are great at product and execution and who are pouring more resources and time and focus (like, where the team doesn't split their time between their product and a major OSS project like ROR) into their offerings? Is there no such competitor that has a better product that poses a threat to Basecamp's retention of users?
