Pros: the design is such that the scaling issues that crippled Reddit are inapplicable. The discovery is deep and multidimensional. The lack of negative reinforcement and minimal positive reinforcement curtails excessive gloryhounding. The nature of interaction builds extraordinarily strong community bonds. Cons: The community bonds also allow outsized personalities to dominate content and silence dissent (yo!). There is no viable discovery or taxonomy topology. The intensely personal nature of discussion increases the stakes so that people become less likely to participate if they feel inadequate, down or otherwise not "up to snuff." The low churn and deeply personal nature curtails rapid growth and keeps the site below the critical mass necessary for self-sufficiency. There is no viable revenue model to cover the site's modest expenses, thus we are all hostage to the beneficence of the site's founders (and donations) to keep the site online. Welcome.
