Vine's limitations held it back. Square video and 6 seconds does not a good video app make. In order to appeal to businesses that would actually pay for video (ad agencies, news) they'd have to completely remake the app to account for different aspect ratios and videos longer than 6 seconds.
When twitter.com already has videos that support those features why keep an antiquated app around?
Too little, too late. I open the app about once every 1-2 months. I never knew about the "watch more" feature. At that point it's just like any other video app, begging the question of, "why use Vine"?
