A while ago, I published a Bash script that will open a Twitter search page to show your old tweets from this day of the year. I have enjoyed using it to see what I was thinking about in days gone by.
So I turned this into a Twitter account.
Follow me to have a link tweeted @ you each day that will show your old tweets from that day of the year. #experimental— On This Day (@your_old_tweets) January 11, 2017
This runs on Amazon Lambda. The code is here.
