WWDC 2021 Twitter Hashflag Goes Live

Ahead of the beginning of this year's WWDC, Apple has set out another marketing campaign on Twitter by enabling a special Twitter hashflag with the "#WWDC21" hashtag across the social network. This year's hashflag includes an icon resembling the thumbs-up Tapback effect from iMessage.

WWDC 2021 Twitter Hashflag
According to Jane Manchun Wong's Hashflag Browser, the new hashflag will last until June 6, one day short of when the developers conference will begin. While unclear, the new hashflag seems to be a "pre-conference" hashflag rather than the hashflag used throughout the conference. Apple, could, of course, extend this hashflag beyond June 6.

Normally, such as in the past with the latest April 20 "Spring Loaded" event, there is a special animation when liking tweets with the corresponding event hashtag. At the time, the WWDC hashflag includes no such animation. However, given it ends on June 6, Apple may be planning other hashflags that will run throughout the week of the conference.

WWDC officially kicks off on June 7 at 10 a.m PT with a keynote where we're expecting to see iOS 15, iPadOS 15, macOS 12, tvOS 15, and watchOS 8. Some tenuous rumors also suggest that the announcement of the long-awaited redesigned MacBook Pro will also make an appearance at the conference.

Every WWDC material Apple has released today has iMessage effects all over it.
So is an update to iMessage the main star of the show???

Hoping for some interesting tvOS and ATV news (that isn't ATV+ related)!

tvOS hardly ever gets any attention, but maybe with the rumors, that might change this year.

I'm going to stop watching IF:
1) The Next macOS is ARM only.
2) If the next macOS prohibits installs outside the App Store.

WTF is a Twitter Hashflag?
I had to look into this as MacRumors didn’t do a great job of explaining it.

From what I can gather, it specifically refers, in this case, to the chat bubble icon with the thumbs up which will be automatically placed at the end of any use of the #WWDC21 hashtag on Twitter.

It’s a “marketing tool” that companies like Apple pay Twitter for. And they’re very expensive. Supposedly the Super Bowl hashflag cost the NFL over a million dollars.

Oh great, another hashflag. Apple's marketing graphic design intern works full steam, wish we could say the same about their product and UX designers. :/
