I suppose the joy is for the NC , may be a retired communication officer from military service or so, that can't live without.
Maybe, maybe not. Many do it simply for the love of radio. Being an NCS of anything is sometimes like daycare. (SSB has their same layers in terms of types of nets, some going to great lengths to see if they may make a successful QSO with someone who's checked in but maybe not heard so well by all.)
One of the things I've found that even the most basic (but well thought out) net does is that it fosters listening and, especially if using the 'QNx' signal lexicon, focus on simple solid practices. Even at my low speed, I can usually get the drift of the typical QSO with someone quicker (as long as their spacing is decent) with about 60-80% copy. In net operations, one needs to be listening and focus on what's happening. Crawl, walk, run. Commo for me is a tool, and we all have our own reasons. I can do 5nn all day with someone 90° to my wire - heading SW into the supposed RF hole of AZ is intriguing to me, as well as the fact that alot of the 4x4 Hams have done a neat job doing what amounts to tactical comms, even if their Jeep Wrangler isn't painted green.
Just one of many different experiences for everyone in ham radio; for yrs trly this simply combines a love of CW with something a tad different (and an excuse to take a nap so I can stay up late - hmmm, my Mom used to say that...).
If an easy QSO to a slow-speed CW net might be for you, give it a shot.
