GIFs are great, but VLIPs are even better. Slack's unfurl and media handling make stuff like this difficult to do, but I think Vlipsy is on the right track.
Gifs are great but when I send my Darth Vader Noooooooo!!! clip I want the full impact of James Earl Jones deep Nooooooo!!!!!
My first inclination is to look for a Vlip to share on Slack. If the perfect one isn't available, and if I have a couple of minutes to spare, I might go to Vlipsy's website and create one. It's not that hard. Plan B is to use a GIF.
I've already made several "Vlips" and broadcast them out to friends/coworkers using the Vlipsy iOS keyboard app and Slack. The website is really simple, straightforward and easy to use.
I use Vlipsy on my phone, slack and use the site to create vlips <3
Their Farmer Fran / Waterboy instagram post is a perfect example of why I need this in my life. A+
Although this is an amazingly fun way to communicate, I think about the opportunity for advertisers to create content in a different way. If content is funny and memorable - the potential reach on VLIPSY could be significant.
