We already have #WebComicDay (web comic appreciation day), but what about *dead* webcomics?

I haven't seen any annual celebrations of dead web comics. Dead means: no longer online, at the original website, and with no credible successor. So for example, garfield isn't.

I therefore declare 13 December as the annual #DeadWebComicDay

That's today.

Hackles.org is my favourite dead webcomic. It's about a bunch of linux nerds working in an office. And aged like fine wine.
