We currently have the ability to embed Youtube, Vimeo, Dailymotion, imgur and SoundCloud content on our postings. Next site update (coming soon) we will also get the ability to embed Metacafe content. In the future we will continue to add the ability to embed content from as many sources as possible. We will also eventually give the ability to upload and monetize audio, video and document files.
The ultimate vision is for MG Social to act as a sort of content monetization vending machine. You plug in your content in whatever form it exists (text,images,sounds,video) from whatever source it happens to reside and MG Social spits out a Coil monetized version of that content available to be consumed within the site by MG Social users.
