I hate to be a downer, regarding a project whose focus is on positive news, but this appears to be entirely built on copyright infringement, and plagiarism. I've only spot-checked a few articles, but those were all tagged "By Ghost", but selecting a unique sentence and searching for that always gave an exact match on other sources.

If you're not writing your own text, you're going to face serious legal issues. Even if you provide adequate attribution (naming the actual author), posting articles that were published elsewhere without the author's explicit permission is copyright infringement.
