We moved to Moose only in the last year, and the reason was that at the time we started LedgerSMB 1.3, Moose was still relatively immature at least in the versions shipping with supported Linux distros. We felt it was an immature technology with too many dependencies to build our software on at that time (2007). After the 4 year development cycle and a release that happened only slightly after Duke Nukem Forever, we had cleaned up a significant part of the codebase, and Moose had changed.
Moose is a bit heavyweight. It may not be what you want in some applications. However, it strikes me as an inspiring example of design done right, and for that reason it's worth learning.
I think this exemplary aspect is why Moose has had the impact it has, not only being somewhat widely used, but also defining approaches that many other object approaches have borrowed. The fact that things are declarative is very helpful.
