Thanks for your insight. I have actually given this a thought.
The first point is that the site is not posting super new content, but stuff that is already popular and has a fair bit of discussion around it.
Another thing is that I ran https://www.reddit.com/user/samacharbot2 for quite some time and what would happen was many people never actually read the article but just made assumptions from the headline. The summary actually helped a lot and even became a starting point of discussion.
I agree that half baked information can be sometimes harmful than no information at all. Ideally how I'd like the website to be used is that people who find a summary interesting go and click the actual article.
Hope you understand my perspective.
