Social Network but Only for Articles

I found this post on Reddit that I think would be a cool idea. It'd be like instagram I think where you have a feed but instead of posting photos or videos, you upload articles that you've been reading and that you want to share with your audience.

So for example, someone like Paul Graham posting articles he found interesting to his followers. I feel like that would be cool and it would give a refreshing vibe from all the visual stuff happening. What do you think?

So... like del.icio.us was, back in the day?
