What is the best platform to setup a vertical social network, i.e. an online community.?

Target market: Consumers spending a few hours a week online, not too advanced

Space: Fashion, entertainment

Visual experience is important, ie video, pics

Super easy to manage and participate

Want control over monetization and hosting

Lots of social features, such as content submission, vorting, rating, polls, commenting, reacting to comments, alerts, messaging platform

Distributed, i.e. gadgets/widgets, feeds, easy to integrate anywhere else

Considering i) ning, ii) Kick apps, ... anything else?

Thank you for the help; fully appreciated
