Twitter CEO Jack Dorsey is selling the first-ever published tweet.

Dorset shared a link to a digital platform called “Valuables” that allows for the buying and selling of tweets autographed by their creators — a kind of digital collector’s item.

The tweet for sale is Dorsey’s first tweet in 2006 which says, “just setting up my twttr”

The current bid: $2.5 million.

Is the world’s first tweet worth that much money? Do you remember what your first post was on Twitter?
