Is this related to one Linux 'fork' or other? =)
Well, I said that without any context, because I think it's true in any case. I thought that saying that was important after reading a discussion where someone suggested having all lists in the same central server, where they could be centrally moderated. I thing that's not good for the community. Of course, all lists here was about lists related to Linux. Not all of them are on vger. And I think Linux is so rich when it comes to features (notice the number of filesystems, for example) because people were allowed to experiment outside of central decision points. Merging them later is important. I always criticize those who don't try to push things upstream. But I find it even more important that people are able to fork/branch/experiment without having to ask for any permission. After all, if it wasn't like that, there wouldn't be software freedom.
