That's why I don't use Flickr. When I snap a picture, I usually want to have the option to share it on a social network, usually Twitter or Facebook. If I don't want to share it, I just use my iPhone camera and save it to my camera roll/photostream. So, why open up Flickr or Instagram if I can a.) share a photo straight from my iOS camera roll or b.) take it in Twitter using my smartphone camera and attach it to a Tweet instantly? Same goes for video and Vine. After the novelty of Vine wears off, will I go to it specifically, as a standalone app? Absolutely not. It will end up an afterthought just like Instagram and Flickr. However, if Twitter makes shooting and sharing a video a seamless experience that comes part and parcel with creating a Tweet (just like it does with photo taking and sharing), it will become a staple. Again, I use my phone's camera and/or Twitter directly to do most of my photo taking and sharing. If Twitter can accomplish this -- and there's no good reason why it can't or shouldn't -- it will do two things: Make taking/sharing video cooler than taking/sharing still photos and, in the process, throw both Instagram and Flickr for a loop.
