What's your favorite "Internet holiday"?

Do you have any favorite celebrations or observances that happen every year on the internet, like the guy who does an increasingly elaborate dance every September 21st or a fundraiser like AGDQ?

My favorite has to be Pizzamas, a 2-week thing in the fall where John and Hank Green (the Vlogbrothers) make vlogs every weekday and sell a bunch of crazy merch based on a ridiculous inside joke, with all the proceeds going to charity! Lately they’ve been working with Partners in Health, helping to improve maternal and infant health care in Sierra Leone.

I loved 9/21! Sadly he’s done now. :frowning:

For me, it’s Species Change Week, and I do really enjoy the internet April Fools’ Day! Which I feel is a little different from how it’s done elsewhere.

He is? Awwwwww.

SCW is super fun, though, and I love all the different April Fools stuff online.
