Howdy Matt! The gray box is supposed to be an embedded Tweet, so I’m not sure why it’s not showing up for you. And my profile picture is a .gif — I discovered some sites let you upload an animated .gif when I was attending a HopIn virtual event. I tried it here on Medium, and it works! It’s easy to do, just record a video and use an online tool to convert the .MP4 to a .gif file. Cheers!
