A couple years back, I spent a day scouring Gutenberg for all kinds of free goodies. Specifically, I wanted to see what public domain science fiction and fantasy there was. I soon realized that the copyrights of a lot of old sci-fi magazines had long expired, and that these stories were all freely available. I didn't download all the available stories, obviously, but I downloaded somewhere in the realm of one hundred, opting for those with the silliest and most dramatic titles ("Spies Die Hard!", "Martians Never Die", etc.). It was a fun way to pass an afternoon, but my attention span is exceedingly short and I mostly forgot about the stories and never actually got around to reading them.
I started to fix that recently when I decided to organize my (no-longer-newish) Reader Seshat (a fine heir to Artemis' noble legacy). Now I read a short story once every few nights, writing up a one-line assessment at the end for the sake of my own forgetfulness.
It's an interesting experience for a number of reasons. There's the obvious one: I'm reading old stories. And these are old, mostly pulp stories. This isn't literature at its finest. It's not even sci-fi at its finest. I think it's best described as sci-fi at its mediocre-ist. But the fact that these are typically sub-par stories makes the reading experience that much more interesting. I try to put myself in the shoes of whoever read these stories back in the 30s, or 40s. I see what type of writing style was popular at the time. I see which character cliches appear again and again. It's pretty amazing.
Then there's the entertainment factor. Because a lot of these stories are ridiculous, and I don't think they were necessarily intended to be so silly. But their outdated styles and exaggerated character portrayals make them a lot more laugh-out-loud funny. When taken in small doses, it's actually a whole lot of fun.
