Threads may be popular for being the app that encourages personal and short conversations among friends and family, but it is no monolith. While it isn't about the aesthetics and pictures, you can take advantage of wanting to share photos and videos of yourself with your intimate friends.
Thus, sharing videos and photos with followers and friends on Threads is an important activity you should not avoid.
The more you share things – including videos and photos- the better your chance of getting more engagements on your Threads account.
