So it's better to just ignore the problems with the documentation? I barely have time to learn the framework—the lack of good documentation means I delete it from my hard drive. No matter how good a framework is, if it's not documented well, it's a buggy black box.
Even criticism that doesn't offer a solution is better than a lack of feedback. Besides, it's not like Google will get all self conscious and stop contributing because people don't think the documentation is good.
