Knowing and talking to several AWA people that watched the AWA both live and on TV faithfully through the 70's, 80's (and in some cases the 60's), it isn't a stretch to say that fans that were into it way-back-when talked about wrestling in a Meltzer-ian way, discussing "insider" rumours, tidbits about interactions with wrestlers in the community, and talking with people that were actually on the inside. Those guys talked if you got to know them.
Same with some of the Montreal-area old-time fans I've talked with over the years, and even discussions with my father and grandfather when I was a kid about when wrestling used to come here and appear on their tv.
What it demonstrates to me is that the community of "smart" fans existed, and the insider information was an enjoyable part of being a fan. It trickled out in smaller doses, but it was discussed amongst the fans of the product at the time, even sought out by them.
The era of the internet and the WON becoming popular brought those smaller communities together in a way that could not happen before, and in time I believe did indeed expand the community of "smart" fans. I also believe those fans existed in greater numbers pre-internet and pre-WON than Jerry will acknowledge, but the broadness of the discussions were limited before either entity became as big as they did.

Also, to Jerry's point about the stories of people having to be smartened up, I think there is some merit to that being necessary back then in some cases, but I often question the things like "Verne didn't smarten me up until I was in the dressing room before my debut". I just can't accept that someone could train for any length of time before realizing how much co-operation was involved to make almost any hold work. We figured that out as grade school kids the first time we mimicked our tv heroes in the schoolyard.
No way new wrestlers and new backstage people could go so long without figuring out the performance aspect of it. I can accept the illusion of a face and a heel hating each other being maintained backstage to outsiders and potentially new insiders, but I imagine the questions would center more around "This is pretend and they still seem to not like each other and are kept apart and I have no idea why".
The fans rioting and attacking wrestlers I consider a separate entity from the above. People went to the matches to lose themselves in the spectacle, and spending two hours geting their blood up watching the matches makes it easy for me to believe the basis for those kinds of stories. I've seen also seen it regularly in minor-pro hockey around here, where fans get so into hating the opposing team that their bus gets egged, players get attacked and there are fights with them off the ice and in the stands, things like that. Hockey isn't "worked" like wrestling is, but the ability of the fan to immerse himself in the game to the point of losing his concept of the game vs. real life is very similar to the way wrestling fans behave.
