OK, here's another one that's good for chest thumping...
I am not a fan of texinfo. It doesn't provide any benefits (to me) over man.
This is a systemic problem. I have a section in my book-in-progress where I
talk about being a "good programming citizen". One of the things that I say
is:
Often there is a tool that does most of what you need but is lacking
some feature or other. Add that feature to the existing tool;
don't just write a new one. The problem with writing a new one
is that, as a tool user, you end up having to learn a lot of tools
that perform essentially the same function. It's a waste of time
an energy. A good example is the make utility (invented by Stuart
Feldman at Bell Labs in 1976) that is used to build large software
packages. As time went on, new features were needed. Some were
added to make, but many other incompatible utilities were created that
performed similar functions. Don't create burdens for others.
Improve existing tools if possible.
