You can also view your replies directly on your profile page, though you can’t see a running log of posts you liked. Twitter has a similar notifications tab, plus you can see all your past likes through the dedicated Likes tab on your profile page.

Messaging 

The difference in messaging features  Twitter vs Threads is simple: Twitter has in-app messaging, while Threads does not. Twitter’s messaging platform lets you communicate with mutual (or any user, depending on their privacy settings) in a few ways. You can send texts, images and GIFs, and even voice messages. Messages is a simple way to share a tweet with another user, too. While you can share a Thread with someone via text, there’s currently no in-app option besides tagging them in the comment section of the post. If you want to reach out a Threads user, your best bet is to try their Instagram DMs.
