You use Twitter. You use YouTube. You use Amazon. You check Reddit. You know what TMZ is. You even been on PostSecret before. But when did you start using all of this stuff? What was your first post? Do you want to know what each of those websites first post was? Yeah you do.
The excellent website ThisWasFirst.com puts together all the original, very first (as in literally FIRST) posts of a collection of the most popular websites on the Internet. It's an amazing collection that shows the first posts from social networks like Twitter to websites like Lifehacker to deals websites like Groupon to gossip blogs like TMZ to official sites like WhiteHouse.gov to everything in between.
On Twitter it was Jack Dorsey checking in.
On YouTube it was this video by Yakov Lapitsky.
This was the first book Amazon sold.
And a few of the first set of postcards that went up on PostSecret.
The internet sure was different before these places existed. No one could have expected what happened when they first wrote their original post.
