I think there are 2 reasons.

One reason is simply that we're better at building the product than the buzz. As it turns out "developer buzz" is not organic, it is something that must be engineered, like any other feature of the product. There are people who specialize in crafting and projecting an image of success in a way that appears authentic. It is a difficult and highly specialized, not to mention it involves a fair amount of "fact distorsion" that doesn't appeal to us.

The second reason is that we're successful without it. When you and I say "developer buzz" we usually mean "HN-reading bleeding edge developer buzz", but 99.999% of our addressable market doesn't read HN. We crave our peer's appreciation and respect as much as everyone else - but at the end of the day, that's not what pays the bills. In our case, mid-aged developers and IT managers looking to remain competitive while circumventing office politics to get their development server in 6 weeks instead of 8 - that's what pays the bills.
