I'm not sure if I should post here or revive one of the two older topics linked, but anyway I started reading US comics around 1990. At that time, in Italy American superhero comics were just beginning to make a comeback after an absence of about 10 years. The new publisher had a lot of old material available, but wasn't certain the general public would be interested and could only afford to buy the rights for one or two books at the time, so they started printing 45-50 pages Spider-Man issues containing one or two Spider-Man stories (by Stern) and/or about half a Fantastic Four story (or even less, by Moench and then Byrne), to gauge readers response. When Fantastic Four proved successful enough, it was promoted to its own book and paired with Miller's Daredevil and the Hulk, while Claremont and Byrne's Uncanny X-Men took its place on Spider-Man. This was then followed by a Captain America (by Stern and Byrne) + Avengers (by Shooter) + Alpha Flight (by Byrne) book. 

To make things more complicated, the editor-in-chief had to be very selective to avoid sales slumps that could get a book cancelled, so entire eras or at least arcs were deemed not good enough and skipped altogether. This meant that the various stories weren't in sync, and you could see a certain team of Avengers making a guest appearance in a Cap story while a completely different one was starring in their own book story just a few pages later.

To make things even more complicated, another publisher bought the rights for another group of characters, including Thor, Iron-Man and various mutant titles, so every time there was a crossover they either had to skip it, or reach an agreement, or publish their own half regardless of when the rest would be printed by the other company. 

All of this is to say that it was a big mess.

Now, in July 1990 my mum took me to the dentist. I didn't want to go but was soon to discover that as an 8-year-old my opinion didn't really matter. Apparently I behaved really well so, as a reward, she took me to the newsstand to buy whatever I wanted. I was a regular reader of Mickey Mouse, but I already had that week's issue. When I was looking around, I saw Uomo Ragno (Spider-Man) #53 (this book here). I liked it enough to pester my dad for #54 the following month, and to look for Spider-Man in other books, which led me to buy Captain America and the Avengers when I mistook a fake Spidey on the cover of this story for the real deal. I was only allowed one comic book per week so I didn't become a regular reader until much later, but since then I always kept an eye out for Marvel books trying to make sense of that messy continuity, and got the odd one now and then.

Do you mean in the Silver Age? The idea of WW riding the air currents in order to fly/glide was introduced with WW#98 (soft reboot). I don't know if Kanigher was just being poetic when he wrote that, but thereafter that phrasing was frequently used to describe her means of "flying." Occasionally there were not enough currents and she'd be unable to fly or glide. 

From what I understand, in subsequent, more definitive reboots such as Post-Crisis,  WW's been able to fly "normally" like Superman--no supportive air currents needed. 

EDIT: WW #98

Around 1965 I had been reading a steady diet of Batman and Superboy. One day at the drugstore comic shelf, I flipped thru a couple of Marvels just to see if I was missing anything. I couldn't understand the language being used in Thor. Another Marvel, probably Tales of Suspense or Tales to Astonish had so many blurbs on the cover that I quickly put it down because I could tell this was some kind of ongoing story and I didn't want to jump into the middle of it. Also on the Marvel books I couldn't tell which characters were the good guys and which were the bad.

Another drugstore I used to check out, had just a few comics on their magazine shelf. Every week it was the same ones until they were finally reduced to one copy of Classics Illustrated War of the Worlds. I finally got so tired of seeing that one comic that I bought it in the hopes that the owner would then put out some new ones. But he didn't

Favorite childhood memory is when i got my first subscription. I think it was Avengers. I remember how they came in this very thin brown "paperbag" sleeve. We had a pretty good mailman so the comic was never bent. I would love getting home from school to see that brown sleeve among all if the white envelopes of bills etc. Then somewhere in the 90's they changed to shitty plastic bags. It was never the same.
