@b0rk yeah, the info experience outside of emacs is pretty terrible. I believe there was a short period where GNOME/Yelp would seamlessly present info pages.
Info manuals tell a story, for power users and learners alike. Link between different concepts. Usually have a tutorial. All of that is missing, for example--not wanting to single out one non-gnu project-- in an avalanche of manual pages.
If you want to learn about Linux (the kernel), wouldn't it be amazing if there was a manual for that? There is one for the Hurd.
