"Under 30"? I'm 32 and I read Ctrl Alt Del in my sophomore year of high school. I was probably on the younger end of people reading it at the time it came out.
I swear the Internet is trying to make me feel ancient đź’€
I read a bunch of webcomics, and I currently read a bunch of manga, mahwa, manhua, web novels, and yes, still some webcomics. I have some favorites, but some aren't that good and are just junk food.
Ctrl Alt Del was never a favorite, nor something I'd check all the time, but every once in a while I'd click through it and read some of it. I probably read it similarly often as Penny Arcade, which didn't really appeal duper heavily to me either.
Yes this is close to my route as well. 90’s and 2000’s webcomics (Penny Arcade, Megatokyo, Looking For Group, Ctrl Alt Delete) and sprite comics (Bob and George), then to Manga Scanlations, Anime fan subs then Manwha, and the occasional Manhua. Currently destroying my neurons by wading through Isekai manga and Regression Manwha power or revenge fantasy nonsense.
But thinking back, those were fun days. The fun continues of course, just have to keep panning for new gold with new authors.
