1.  Where is the best introduction to what GNU is all about, to be found,
    preferrably online?  (Don't try to explain here, just point me...)

2.  After spending many hundreds of hours working with certain commands,
    you really start to notice the problems the command has, and minor
    improvements (keeping in the spirit of the command's format) which
    would greatly increase its functionality.  I realize they're probably
    already aware of and and have fixed most of these short-comings, but...
    do the GNU programmers welcome suggestions, and if so, how does one
    find out who to contact for what (in particular, for sed)?
