The idea is that a User can collate some articles from around the web, leave a commentary and turn it into a sort of shareable magazine.
This has been attempted many, many times. As far as I know no one has ever managed to make it work profitably.
Interesting sidenote (well, I think so) - Bastian Lehmann started a platform called "curated.by" for collecting articles, videos, tweets, etc before he started Postmates. I saw him do a presentation about it once (as part of a Difference Engine accelerator demo thing).
