There's a product that myself and another programmer have been working on for the last couple months. My tech lead threw it on the test server, comes back a couple days later and says, "The thing is working fucking awesome".

Best description ever.

But on a more serious note, if you aren't getting feedback from your testers, clients, whoever; you need to start soliciting it. Lack of feedback means a lack of refinement of your program. Generally "no news is good news", but not in the case of software development.
