There are never dumb questions, only practical and valuable examples of areas for improvement in documentation and/or related collateral (tutorials, cheat sheets, FAQs, etc.).
I actually interact with teams that bring a lot more revenue and is more highly visible to the public. And, again, I may be lucky here, but all the way up to my SVP are nice. I may have been lucky, but I think it's more an issue with people generalizing some issues. I'm not going to generalize my experience either, but I had to offer a different perspective.
Honestly, think about how many companies let their nerdiest of engineers be the public face of projects. The reputation is easy to come by when your front is not a "people person".
They are incredibly helpful, and very tolerant of newbies like me who sometimes ask dumb questions...
