Well, it's rather inaccessible/unappealing to the majority of people who use sites like Reddit, Twitter, Facebook, etc, so that probably has something to do with it. There's a pretty strong correlation between 'folks willing to use a site that looks like it's from the 80s without mobile app support' and 'folks with meaningful things to say', at least if you take the average front page content on other social media sites as a baseline. Also because Dang does a really good job with the moderation, whereas most of these sites farm it out to the lowest bidder.
