Could this be used to model the lifecycle of a Reddit post? What makes one thread get more votes and be replied to more often versus another similar thread posted at the same time. Is there a time when a comment is more likely to be voted for, based on wall clock or relative to the start of the thread. What topics are more likely to receive votes than others. Is there a minimum time between when reposts can be posted and still get upvotes. What are the most reposted things on Reddit. Why do people keep voting for reposts.
