"Yahki enables you to tell your own story - use the web content, links, photos& videos to create a new story & share it with your friends on facebook and twiiter"
Well....not quite. This app is NOT about storytelling. It's more a tool to share and comment on content that you select from the web -- a light version of content creation. So they are using the word 'story' very loosely.
If you want to curate content, this could work for you. If you want to really share stories, this is not the tool.
