Twitter is experimenting with a couple of new variations for tweet interaction in an effort to boost engagement.

As shown in the image above, Twitter has a new layout mock-up in place, which includes the following changes:

• Threaded replies to individuals’ responses to see who’s responding to what within a tweet reply chain
• Color codes changed to purple for responses from the original tweeter, and blue for users’ reply
