In addition to what @junaru mentioned [0], about copying pasting GIFs, I would also add that I can send GIFs easy in emails and be assured it will be rendered in the email for the recipient. Unlike videos, people don't have to click multiple times to see them.

I've found this very convenient in sending small clips of screen recordings using ScreenToGif [1].

Of course, what would be really nice is if one could play / pause the GIF!
