There is a recent PEW study showing that 40% of people would prefer a no-tracking search experience. And yet a very small percentage of people have ever heard of DuckDuckGo. As a result, we think we have a lot of room to focus on making the product better and growing, and that is really our future plans in a nutshell.
In hindsight, there are always activities you realize now were a waste of time, and it is easy to say you wouldn't do them now, but in the moment it is much harder. So in general, what I've been trying to work on is making sure we're always working on the right projects, and scoping them right, given the information we have in front of us. I would have liked to be better at that earlier, but in general I wouldn't have done that much differently.
