Twitter added a “discover” service that makes it easy to find someone’s very first tweet.

To give it a try, go to your browser and type:

https://discover.twitter.com/first-tweet?username=xxxxx

Replace xxxxx with a Twitter name. For example, let’s take a look at Tim Cook’s very first tweet:

https://discover.twitter.com/first-tweet?username=tim_cook

When the results page loads, click on the link that says “Check out the first Tweet by tim_cook”, which will take you to a page that says:

Visited Retail Stores in Palo Alto today. Seeing so many happy customers reminds us of why we do what we do.

Nice!
