"This is part of our work to make Twitter more conversational," the micro-blogging site said on Friday.
Lately, Twitter has been exploring new ways of protecting its users from hate, abusive content and fake news.
"Because of this 'subscribe to conversation' feature, users would not need to like or comment in a thread to receive updates and this could add a bit of anonymity," Engadget reported.
Although, there was no indication yet if or when Twitter will deploy the change platform-wide
Earlier this week, the company launched its beta app "Twttr" that comes with special colour specifications for conversations. It has also been experimenting with profile preview feature and an "original tweeter" labels.
