Thanks for sharing! I founded the group since I was fed up with the Computer Science Facebook group for Cornell -- while there was occasionally interesting CS content, it was flooded by a lot of stuff that's either no longer interesting to me (a lot of it is Cornell undergraduate centric, while I'm now a graduate student at MIT), or just meme/jokish in nature. My goal was to make a group with interesting, thought-provoking content and better quality discussion. If this appeals to you, feel free to join and contribute.
There is a facebook group, computer science real talk. https://www.facebook.com/groups/500102603385910/ Things in there are interesting to grad students. It seems to start as a place for cornell cs graduate students. There are people talking about STOC papers in there, neat.
