Hulu's GIF library offers visuals for your reaction tweets
Websites like Giphy and others are useful for supplying a GIF to get your point across. Hulu is looking to help too, so long as your thoughts/feelings/hot takes can be summed up with an image from one of the TV shows streamed there. The company launched it's own repository, which is appropriately housed on Tumblr, allowing you to search for specific shows, actions and reactions to find the perfect moving picture for your needs. Heck, there are even gems like this one from Star Trek: The Original Series.
