I have a tool that is called https://www.MyTweetAlerts.com - it is a new and better way to search Twitter. Email alert for Twitter. In that tool I can find tweets that have more than x number of likes or retweets about some subject and in that way spot tweets before they go viral or use it to find tweets that have a lot of likes or retweets (that are currently trending).

For example I did create this page to show all coronavirus tweets with more than 10K likes:

So I am really interested in this topic :)
