80% of twitter users are on mobile That goes up

That goes up to over 90% when you talk about users watching video
Why? Most would rather watch then read on their phone.
Don't even want to hunt around for a link
Just tag a gif or video, make them interactive and make life easy for your audience you are communicating with, now two ways!
Rory said it best, If your going to post a video, wouldn't you want it to be interactive?
Interactivity in gifs and video will be like when sound was added to movies. That much more engaging for the audience.
Take it one step further. When say 10%-20% of all gifs and videos are interactive, for the brands/people that don't have interactivity, users will click on their gif/video expecting it and will go someplace else. Lost opportunities.
