How could I measure it?
A nice to have feature that could increase engagement and retention on twitter is resurfacing liked tweets or bookmarked tweets by the user every now and then on their timeline feed.
There are several reasons a user likes a tweet:
And many more
More often than not, most users like a tweet because they appreciate its content. They like the content of the tweet for its usefulness, humour, information, and so on. Liking a tweet invokes positivity.
The issue is once a user likes a tweet, it is stashed and hidden from view forever unless it is deliberately rebooted by the user or someone else.
Resurfacing Liked Tweets
I believe resurfacing some of the good tweets every now and then on the users timeline will induce positivity as it will take the user down memory lane and they are able to relive a moment. This in turn can cause them to reshare the content which in turn increases engagement and retention.
This can also work for bookmarks. If bookmarked tweets are meant to be returned to sometime in the future, then it may help to bring them into the view of the user every now and then as a reminder to engage with the content of the tweet. It will work similar to resurfaced liked tweets
