I have a web piece up about seminal Archie/Betty/Veronica moments (as seminal as you can get when you have a relationship that never changes), tying in with the famous news about the Archie "proposal."
And while I understand what Michael Barrier means when he says that "When I read Li'l Abner in bulk, the harsh mechanical qualities of Al Capp's strip force themselves on me," I find Li'l Abner holds up better than it's given credit for (better, in my opinion, than Pogo), and the current the current hullabaloo over Archie's proposal is an example of why Li'l Abner remains relevant: they're using all the tricks that Al Capp parodied in the "Fearless Fosdick gets married" storyline, and we're still falling for them.
Also, while I don't want to turn this into a Peanuts discussion blog, I don't agree with the idea that Peanuts "softened" in the '60s; on the contrary, it was a much "softer" strip through most of the '50s, more focused on day-to-day gags about the things kids say to each other. It was in the late '50s and early '60s that Schulz started to move into longer storylines, more direct addressing of contemporary events and issues. Not that there was anything wrong with the strip in the '50s, but the comedy became much sharper and more biting around 1959, staying that way through the mid-'70s.
And while the increased emphasis on Snoopy might have had some negative results, it also helped the strip expand into subjects it couldn't tackle before: because Snoopy was the only character in the strip who was not a child (and in his fantasy life he always imagined himself as an adult, not a child), it allowed the strip to take on things like the space race, college life (Joe Cool) and, of course, war.
I will say, though, that the Snoopy emphasis of the early '70s is an example of how something can be more of a problem when you read strips one at a time, rather than in bulk. When I read the 1971-2 strips in the new "Complete Peanuts" volume, the huge number of Snoopy and Woodstock strips doesn't bother me, since most of them are funny. But when the Peanuts website was running 1971 and 1972 strips one a day a few years ago, the Snoopy/Woodstock stuff irritated me because it seemed there were too few days that went by without those two. In a book, you can just turn the page to find a strip with the other characters. So that's an argument against my idea that strips come off better in day-to-day reading.
