I find a lot of good insight in this article (despite the classically linkbait title). Absolutely, execution is difficult; there a ton of difficult problems to solve on a site like this, e.g.: How can the system allow noobs to participate and advance without incentivizing sock-puppets? Are voting circles good (increasing participation) or bad (decreasing honest assessment/diversity of content)? No site is going to get it all right, but I think it's both appropriate and useful to periodically assess: what are some of the Digg solutions that didn't turn out to work as well as alternate solutions? On a few points, the article doesn't persuade me, including the claim that a twitter-like mostly-personalized homepage beats a community-wide homepage: maybe yes, maybe no. But several other strategies adopted by Digg do seem to be problematic over the long-term, and kudos to the author for highlighting a bunch of relevant ones. Bigger kudos to reddit for pretty consistently adopting smart solutions to these same problems.
