That is exactly why I love DDG. I almost never get spam, but the fact that you want to make it even better is so awesome. Seriously, DDG's killer feature is a founder interacts with the users.
In other words, how much fun are you having, and how long is that going to last?
EDIT: A legitimate question, as Gabriel has cited fun as one of the perks of going DDG. How are people reading this as a negative comment/question? It was meant as a prompt to respond to the parent.
Doesn't scale well, how sustainable is this going forward.
