In the end Dist::Zilla doesn't need a copywriter because it's not trying to sell itself to anyone. Its main virtue, in my eyes, is being useful to me. If other people get mileage out of it, that's cool, too.
As for the "dzil new" command, which is the "Module-Starter-like" bit, it's very young. I think it's also very good and has a lot of promise, but its main form of documentation right now is a screenshot of it getting used in my blog. The explanation for this isn't interesting to many people, and goes something like, "documenting it before the global config subsystem that will enhance it is complete would be a waste of time because of the changes to docs that it would require later."
That said, if you stop by irc.perl.org #distzilla, there are almost always people there who can help you use it. I think you will find it much more flexible than Module::Starter, which was very hard to extend as time went on. Its that technical inflexibility that led me, in part, to stop using it.
