Of course Twitter made an update to make thing setter than what they already are. If you've been on twitter for a while now, you understand that when sending a direct message, there were no images aloud to be sent. That has now all changed.
Now when sending a message, you can send as many images that fit the character criteria. IS this something you think can benefit or hurt twitter in the long run? These kind of updates will always help twitter in being a top social media spot.
