Any mistakes are my own. Basecamp is a modern software company that (by many estimates) generates millions of dollars in profit each month.
Promise not to promise
Since the beginning of Basecamp, we've been loath to make promises about future product improvements. We've always wanted customers to judge the product they could buy and use today, not some imaginary version that might exist in the future.
The wrong time for real-time
Chat puts conversations on conveyor belts that are perpetually moving away from you. If you're not at your station when the conversation rolls by, you'll never get a chance to put in your two cents. This means if you want to have your say, you need to be paying attention all day (and often to multiple rooms/channels). ... Chat is great for hashing stuff our quickly when speed truly is important. ... It's also great for watercooler-like banter ... building a camaraderie among people during gaps in the workday.
