You may ask "What about in-house applications, for one company?". In-house applications are already dominated by IE and ActiveX. That's not gonna change overnight. Or maybe I'm wrong.
GDevs (Geeky Developers) are rightly proud of their creations. The problem is when they fail to see the surrounding world. Now almost famous blog post from Ben Collins-Sussman about two types of programmers contains this pearl:
Fortunately for OpenSource community, people like John Resig, Andreas Gal, Mike Shaver, and Brendan Eich are in the 20% crowd. Let's just hope they won't lose sight of the rest of us :)
Shocking statement #1: Most of the software industry is made up of 80% programmers. Yes, most of the world is small Windows development shops, or small firms hiring internal programmers. Most companies have a few 20% folks, and they’re usually the ones lobbying against pointy-haired bosses to change policies, or upgrade tools, or to use a sane version-control system.
Shocking statement #2: Most alpha-geeks forget about shocking statement #1. People who work on open source software, participate in passionate cryptography arguments on Slashdot, and download the latest GIT releases are extremely likely to lose sight of the fact that “the 80%” exists at all. They get all excited about the latest Linux distro or AJAX toolkit or distributed SCM system, spend all weekend on it, blog about it… and then are confounded about why they can’t get their office to start using it.
