I like Vine. I like the concept and in particular, I like how fun it is and simple to use.
I believe Vine will do the same for video case studies that Twitter did for blogs. How can you tell a story in a six second video clip that continuously rolls? Well the same was said about 140 characters but people simply got smarter about how they communicated their stories and it exploded.
You can see here is an example of a Vine we made in the office which although simple and rough around the edges, I believe gets across our story more than effectively.
From a short six second clip you can see that my PR agency works with Kaspersky Lab, that we ran a campaign around safer internet day and generated some strong national coverage. It is enough to whet the appetite and hopefully if people want to know more they will ask. Ultimately, I can see these Vines linked to longer form video case studies with a six second Vine being essential to getting someone to click through and invest two to three minutes of their time watching a longer form case study.
