XKCD Isn't Funny - #1581 - Birthday
As happy as I am that the copyright industry has lost this one, this is not something that deserved a whole comic to itself. And if it did, the comic deserved some context. Even the people who knew that "Happy Birthday" was copyrighted wouldn't know what this comic meant if they hadn't heard that said copyright had been declared invalid.
I understand that this isn't supposed to be a joke, but it isn't even cute. At least #1000 had all the different stick figures and we can nostalgia trip a little. This one only has twelve, and you can't tell who four of them are.
This comic is too long to be a tweet, but it definitely shouldn't have been a comic on its own. Everyone knows you have to thank the readers if you're going to make a content-less anniversary post.
I have to say, though, without XKCD, I think a lot of us would have a hate-shaped hole in our collective hearts. I wasn't around for xkcdsucks' golden age (I was a Cracked guy, before Cracked went to shit), but I'm betting any readers that came over from there can remember one comment section they had a particularly time in. One time I even met a former anti-fan from 2008 on Omegle and I got him back in by showing him XIF, it was kickass. And when you think about all that, how can you really truly want XKCD to end?
So, Happy Birthday, XKCD. And many more.
