That's a feature, not a defect. I run Debian on a bunch of servers. I like that it changes slowly. I like that it's not trying to be the bleeding edge. I like that migrating from one major version of Debian to the next is reasonably painless. For running a bunch of servers, I want something that follows the tried and trusted, not something that rides on the bleeding edge and something that has an absolutely rock solid packaging system. This is Debian, and it's why Debian is the right tool for this job.
If you want a distro that develops, there's always Ubuntu or Fedora.
