I enjoy Reddit, and have to admit I have not encountered some of the issues they describe in this episode of Off Book. 

Since its creation in 2005, Reddit has grown into one of the most influential communities on the internet. More than just a content aggregator, it generates information and new content, and has given birth to intriguing collaborative projects that reflect a particular group character and value system. The Reddit community has become so active that it has had an impact on recent political events like SOPA/CISPA. And like any real-world community, it also has its share of internal social issues, forcing it to grapple with its commitment to free speech and the lawlessness of the internet.
