Thanks for posting this article! I totally agree that every software developer should use a package manager to manage his dependencies. Downloading binaries with a browser is totally 1995.

There are a couple more package managers I missed in the article. For example the new package manager for PHP, called composer. It is very similar to NPM from NodeJS. And there are already more than 17K projects on the central repository. You can check out the numbers here: http://www.versioneye.com/php

Another really big one is Maven for Java. There are more than 80K Project available through Maven Repositories. Maven is the most complex package manager I know. But I guess that is natural for Enterprise :-) I prefer more simple package managers.

On this page you can see how many projects are available through each package manager: http://www.versioneye.com/statistics. Bower and other package managers will be integrated in the next weeks.
