This would be great, except that it's impossible to "support Linux". You can support Debian, or Gentoo, or CentOS, or Slackware, or one of the many other linux distributions; but the fact that your code works on one distribution doesn't necessarily mean that it will work on another.<p>I'm dealing with this with tarsnap right now -- I know the code works on FreeBSD, NetBSD, OpenBSD, OS X, and OpenSolaris; but for Linux all I can say is that it works on Debian, Ubuntu, CentOS, Slackware, Gentoo, and RedHat. Does it work on SUSE, Mandriva, Xandros, MontaVista, or Linspire? I don't know. (But if anyone here runs any of those, I'd be happy to hear from you.)<p>Yes, I could install N different distributions of linux and test them all; but testing on N different distributions is much more work than testing on 1, and many people simply won't have the time.
This is the model that brought fame and fortune to Bungie.<p>"The team focused on the Macintosh platform, not Windows-based personal computers, because the Mac market was more open and Jones had been raised on the platform."<p><a href="http://en.wikipedia.org/wiki/Bungie#Founding" rel="nofollow">http://en.wikipedia.org/wiki/Bungie#Founding</a><p>They had a clear and open field making quality games exclusively for the Mac platform, and this brought them a devoted following and a steady flow of profits. They later branched out into Windows, and of course Microsoft bought them out so they would focus predominantly on the XBox.<p>So, while ignoring Windows indefinitely may not be a great strategy, ignoring it at first can be.
This was nice, pretty much straight to the point. At Dropbox we've noticed disproportionately more Mac/Linux users (relative to the "worldwide norm" or whatever that means, which is pretty standard). More importantly, we've definitely noticed disproportionately more vocal Mac/Linux users. We started as Mac and Windows but "investing" in a Linux (ok, Ubuntu/Nautilus to be specific, but it tends to work in most distributions and can work without Nautilus) client has certainly been worthwhile.
