Which is not surprising. I do a webcomic, and have no day job to distract me from it, and yet sometimes I can't even manage one page a week, let alone the six B&W strips and one Sunday strip that being a Syndicated Cartoonist involves. I have a friend who's doing the syndicate gig right now[1] and she's basically impossible to get ahold of because she's always got to stay on top of her buffer.
It's kinda like coding for video games. It's a dream job but the reality is that there are a ton of other people clawing for the same position so you better work your ass off, kiddo!!11!!!. Well, okay, maybe less of a dream job now that newspapers are dead but you know what I mean. That shit burns you out but good.
But this man is not a SC. He is Bill Waterson. If he wants to have a panel once a week, in full color, only on thursdays any newspaper editor who turns him down is an idiot.
As for making him a web cartoon artist, all you need would be hosting somewhere, a server that can handle the traffic and one message to whomever moderate the Facebook Calvin and Hobbes Fan group, plus a twitter account that sends a message each time a new cartoon is published.
Who knows? Maybe this little thing he did with Pastis was him testing the waters. He might have been asking himself "Do I still have it? Do I still WANT to have it?" by drawing these. Maybe he's toying with some sort of return. Maybe he's about to drop some awesome personal graphic novel that's been brewing this 20-year-sabbatical. I know damn well Universal/Gocomics would kill to set up a new presence for him on pretty much any terms he wants. Half the web cartoonists he met via showing up on Stripped! would probably do it for free.
But does he want it again?
I mean, he retired into aggressive anonymity for twenty years. He might have recharged. He might still be completely burnt out.
We can't know. And that's entirely what it rests upon.
Sure, it's just wishful thinking, but it wouldn't be that hard to give him an outlet to do as he pleases, assuming he wants to do something.
I'll be darned if he couldn't find someone to work with who could handle getting his work online though. It's mere wishful thinking, but he could draw and communicate (or not) in whichever way he wants, and some trusted friend and gatekeeper handles all of the scanning and online stuff, which could be kept very simple and noncommercial. No ads, twitter, comments section or any of the usual "social media branding" stuff, literally just a page with a comic on it.
Sigh. Man, I still miss Calvin and Hobbes.
