A website to read and share contents related to startup ecosystem

What about a website where people can submit and read contents related to startup ecosystem. I just came up with an idea, a website where anybody can share contents related to startup and entrepreneurial circle. And people can mark those content as HELPFUL. You know as a person if you are attached with the world of startup, business and entrepreneurship you like to read content that are related to your domain. Also many people read various blogs, websites or watch various videos which may not be possible for other person as an individual to go through. It is very much possible that we generally miss out some grate piece of content everyday. Therefore what about an idea of centralised website where other users can submit links of the articles or videos they found interesting and worth sharing. Maybe a blog or video shared by some other person could help you in some way. It's all about knowledge sharing. Here we help other users by sharing valuable piece of information, that they could not find themselves ever. What you guys think about this concept, please share our reviews with me. Thank you,
