The interface for Indie Aisle will be similar to Twitter, or Facebook, or other social media sites. You will have your dashboard of posts made by feeds that you're following. And you will be able to interact with each one by liking, reposting, and commenting.
And you will be able to make your own posts. Either a short text post, an image, or a longer form article. Other media includes MP3 audio and MP4 videos. And your posts can be downloadable files as well for things like ebooks. This means that posts will also have the option to set a price to sell your content.
You can also setup a community where you allow only people that are part of your community to add posts as part of a message board.
It all starts with a post, a thought, an update, an idea.
