targeted industry -> people who are exposed to it -> people who actually investigate it -> people who actually download it -> people who actually try it once downloading it -> people who continue to use it.

You want to get as many people to that last step as possible. Unless you only care about getting closure people, appealing to a wider base will help adoption and broadening the base vocabulary is the first step.

Right now this is only appealing to closure people, and statistically only a small subset will actually go through the trouble of giving it a try. An even smaller number of people will switch to it full time. Considering mainstream development doesn't happen in closure (yet), your first part of the funnel is already pretty freakin' small.

Just my $0.02.
