We could name hundreds, probably thousands, of OSS applications that are more popular than the laughably obscure #4 and #5 in the list in the article (not laughable in the sense that I mean to devalue their work, just that they are so clearly for an extremely niche user, and that user is a programmer).

I don't really care to argue semantics about what's a library vs. what's an app. Because many libraries have a UI and many apps have an API; that's another discussion, really (though, you've got tens of millions of people using Firefox through the UI daily and maybe a few thousand using it as a library daily...I know where I fall on the "is it an app or a library" continuum).

But, seriously, this article looked at one pile of data generated by a site that is entirely by and for programmers and declared that the entirety of OSS is represented by that data. The more I think about it, the more ridiculous, and maybe even offensive, it seems.
