But then I read this about GRAMPS, and lost hope:
GRAMPS is available for Linux, Windows, OSX, BSD, and Solaris, but the Linux versions are generally the most up-to-date.
In other words, GRAMPS has no chance of succeeding as a mainstream open-source project because it is skimping on the primary genealogy market: Windows.
Much of the world's genealogy is done by the older generation, a generation that isn't likely to have Linux running on their home desktop. While my grandma can run Linux, she and her crowd simply aren't going to be the ones to find and install GRAMPS.
Yes, Linux users can enjoy genealogy, too, and need not be using the same Personal Ancestry File that much of the genealogy world uses. But that's not the point.
The point is that the world would be better off having a common, open platform upon which Windows, Linux, and Mac users were both building and doing research. By privileging the least likely platform for mainstream users (i.e., those that do most of the genealogy), GRAMPS is locking itself out of its best chance to build a system that suits their needs. Much as I dislike Windows, it should be the first platform that GRAMPS supports, not Linux.
Developers will go where the users are. Genealogy users are not on Linux.
