I loved the letter section of the comics. I suppose the internet takes care of that now. I'm a little too nostalgic to really equate the letter section with the internet.I remember writing a letter to Marvel Comics in response to Conan 218 - May 1989 - remonstrating with them for the racism in that issue, and suggesting to them that they did not need to follow in REH's footsteps in that respect. (I don't believe my letter was published.)
I remember how the letter section made me enjoy comics even more thanks to keen insights by other readers.
One of my favourite runs as a kid, which ironically dealt with racism, was Green Lantern's Mosaic (92-93) which saw a whole bunch of peoples uprooted from different worlds and placed together rather haphazardly for an exercise, to see if they could construct a cohesive society with disparate races.
