I can tell you one thing: there are many, many people who have benefited from the fact that Bundler fixes a boatload of issues for developers and in general makes my life, and their lives, better, even if we have to type "bundle exec", which I have conveniently aliased to "be" (try it).
I'm also willing to bet that a lot of people would benefit from this project if Yehuda takes it on. I don't know if he knows Objective-C either, and I don't care. Why? Because this is a guy who knows how to produce useful software. No, it doesn't let you produce music in your browser, or program beats in Ruby. But it is useful.
Archaeopteryx was the first time I came across you in the Ruby world and I thought it was really cool when I tried it out. Then again, I didn't find it particularly useful. I find Bundler useful every day, and I'm willing to bet lots of other people would too.
I realize I'm making this personal, and I'm sure that opens up a great opportunity for you to disparage my own accomplishments, or perhaps engage in some deliberate heckling and mockery, as opposed to the mockery you mistakenly perceive in a program's error message. I'll save you some time: I suck at programming compared to Yehuda, and I'm probably not as good as you are at it either. But one thing I'm far better at than you is appreciating people for their contributions instead of behaving like a jerk. So give it a rest, it's tiresome and juvenile.
