How to Go Back and See Your First Tweet
When you initially load your Twitter page, only your most recent Tweets show up on the screen, but if you're feeling nostalgic for old times, you might also want to check out your older tweets. To view old tweets, continue scrolling down to the bottom of your Twitter page; each time you reach the bottom of the loaded page, the website loads more tweets until your very first tweet is displayed.
Log in to your Twitter account. Your Twitter feed appears and displays your most recent tweets.
Press the "PGDN" key on your keyboard to reach the bottom of the page. Alternately, scroll down with the mouse.
Wait a moment for the next set of tweets to load. Press "PGDN" to reach the bottom of the page again and load even more old tweets. Repeat this process until your first tweet appears at the bottom of your feed.
