I'm a (very happy) Perl (5) dev and although I've attended lots of Perl 6 cool presentations, I haven't took the time to learn it yet. My reasons are related to the fact that there are not that many commercial opportunities with it just yet. That is a thing which I expect to change in a relatively short time. I've already seen a few job posts looking for Perl 6 developers, which, given the language is declared 'production ready' for less than a year is a pretty amazing stuff.

Also, there aren't hat many libraries in its ecosystem yet, a thing which can be a plus for devs who want to create a name for themselves in the open source world by implementing/translating libraries with a large user base potential.
