According to its FAQ, Photovine is apparently more about connecting with people than sharing photos with your friends. The service lets you build a photo collection around an idea or theme using photos submitted by other members of the social network. These collections are called vines and include a caption or theme like mountain hiking. The vine will grow when users begin adding their own photos that contribute to this theme.
It’s “uber public” and meant for people to share their personal experiences freely so they can connect with others. According to a FAQ, images will be moderated so this freedom of expression does have its limits. That likely means no Weiner-style crotch shots, fellas.
