Readers are a careless lot though. The bin boys of my youth who let wheat dust gather on the first DD/Spidey crossover anticipated today's shortage and consequent high prices only by virture of their contributing to it. They will as likely crease the pages, swap with friends, read what's in the library, come across some good ones in the waiting room or servo, even in bus shelters or on trains. Even with series they like, they'll threaten its viability by waiting for the trade paperback (collected edition). But, sure there are readers who let the guy behind the counter know that it's worth stocking All Star Batman and Robin by buying it every month.
It's a broad church containing readers of Elliot S! Maggin Joker stories, readers who are drawn to Ernie Chua's art, readers who happily continue to buy their favourites regardless of recommendations or hot books.
Some readers become collectors and seal the books they used to pore over in plastic bag and backing board. And there are readers who develop their interest in Frank Giacoia to the extent that they are more than readers, they're fans.
