I'd love to hear your opinion on our project - KeepOne.com
It's a platform to collect and share content from the internet. Our goal is to give users freedom to share their favourite content, as well as allow them to keep their stuff private - if they want to keep some stuff hidden. We're at Beta version right now, so all the suggestions will be considered.
Hope you can spare 5 minutes and help us make a better product!
