Build a Website for curated news

The project is to design and build a website that provides automatically curated news about a niche technology topic (I will provide the topic privately). I am open to the platform it is built in - main concern is answering the requirements below. - The site will use feeds from twitter and other news sources, and be able to avoid duplicate posts from different sources - The site will be visually appealing where news are divided in categories (to be defined) - Examples of curated news website here: [login to view URL] -The site should have a section that features videos related to the topic (from youtube or other video sources) that update frequently (more than once a day) -The site should have a section that features books about the topic that can be bough from affiliate sites (probably amazon) - The site should have a section that features hardware related to the topic that can be bought from affiliate websites (probably amazon) - I see this as a main source of revenue so it should be appealing and well organized. -The site should allow in the future for sponsored ads (e.g., ads), potentially inline ads, and other ads Requirements to be discussed: 8. The site will have a section where visitors can upload their articles, comment on other people's article 9. The site will have a section where visitors can upload their videos
