I've always thought Rich would have enjoyed scans_daily for the mingling of veteran old school fans with newbies wanting to learn more about comics history, because Rich was all about that. But he never thought of himself as a celebrity of comics fandom, so the idea we'd ever be talking about him here would just baffle him.
And yeah, everything Mark Evanier says about him in the link cited above is spot on...though the included photo bugs me, because his health was already in decline when it was taken and it doesn't really look like Rich.
