Yes, it was Bob C. who started the trend, AFAIK.
Yes, SonsofThunder, you have the right approach about them. If your mix sounds good on the NS10s, then they will work elsewhere.
For those who don't understand why NS10s were popular and complain that they are fatiguing and sound bad... basically that's your answer above.
There are several additional points to make:
-They were not meant to be played loud, and most engineers who don't understand them were using them at inappropriate SPLs.
-They do sound different depending what is driving them. Don't assume it's the monitor's fault until you've heard them with several good amps.
-It's a mistake to use them in a large room or at a distance. Again see the first point about high SPLs. Of course that causes fatique.
-The early NS10s did indeed have a nasty peak, but you learned to listen through that and it helped prepare you for the real world where your music would be heard.
-The later NS10 Studio versions sound quite good.
-However, they are not meant to sound flattering or glorious and comparing them to much more expensive monitors is missing the point of their utility.
-I, and many engineers, preferred them in many instances because you were no longer seduced by a glorious sound and could immediately get to work.
-Really flattering and good sounding monitors are HARDER to mix on because you have a harder time sifting through what is really going on -- because everything sounds better, everything sounds good! How can you mix when it all sounds good? You can't. (You don't want rose colored glasses mixing.)
-If you need references that you feel you are not getting with the NS10, flip the switch and listen for a minute with bigger monitors. You are not married to the NS10 throughout the mix!
-I personally dislike Genelecs. Blech.
