It's over for Vine. A brief post published today on Medium says the Twitter-owned platform will be discontinuing its services in the coming months.
The following is an appreciative excerpt from the announcement:
Thank you. Thank you. To all the creators out there — thank you for taking a chance on this app back in the day. To the many team members over the years who made this what it was — thank you for your contributions. And of course, thank you to all of those who came to watch and laugh every day.
There's nothing to worry about if you're someone who became known by many on Vine. Everything ever posted will remain live, and you'll still be able to access and download content without a hitch. Both the website and the mobile apps will continue to exist; however, that's not to say things won't change in the future. Users will be notified if any changes are ever made to the website or app.

Vine's team and Twitter aren't saying exactly why the three-year-old platform is shutting down. Even the fate of the team behind Vine is going unmentioned. Twitter seems to be keeping anything related to Vine's shutdown a secret. One theory is that Twitter never figured out a way to monetize Vine, but we'll never know the true story until an insider spills.
