Twitter updates Vine to include a list of recommended friends to follow
Recently, a new setting was added that allows you to view your Vines in 720p HD from 480p. To make sure that you are seeing your six second video loops in the higher resolution, go to your profile page and tap on the "settings" gear. Click on "your content" to see what resolution your Vines are being seen in.
In addition, Vine now has an improved search function. Previously, searching on Vine was limited to hashtags and users. But last month, changes were made that allow Vine users to search for a specific phrase and find relevant content.
The app is a free download and is available for the iOS, Android and Windows Phone platforms.
