Sure, you can find some great bits of information there, but when it comes to something like a science subreddit, you have to be very strict in moderating comments that might mislead people (r/askscience does this very well). There is NO room for anecdotes or personal assumptions when it comes to discussing scientific articles. It really is all or nothing, if you allow any non scientific-based discussion, you get something like r/space which is (was?) one of the worst subreddits in my opinion.

Also, there is a huge political bias over on r/science. I see this as a huge problem with most of reddit actually, but people should forget about political bullshit when it comes to discussing scientific facts. Unfortunately, this is not the case and people begin to discuss the moralities/logistics of drug legalization rather than discuss the science presented in the article. I have gotten into many debates on that subreddit and have, attempted to, correct so much misinformation that I was just forced to unsubscribe a few months ago because of how rage-inducing it was. I'd stick to r/askscience.
