Re: Variety Versus Fragmentation
This relates to something I noticed during the "Unix Wars" thirty years ago: there seemed to be a lot of effort devoted to compatibility for programmers but a lot of differentiation in the system administration tools. This surprised me because I thought that the system administrators would have more influence on purchasing decisions than programmers.
I still see the same thing today among Linux distros and BSD variants: the core application software is all very similar, compatible, portable, but configuration and system management are all very different.
