One of the things I always disliked about the original Digg was their threading. The slashdot like feed where the oldest comments were at the top and there was only one level of replies tended to encourage the "first" comments and harmed the quality of the discussion. I was glad to see it use a reddit-like comment thread for the new site, but it also meant there wasn't much reason to use it over reddit.
I'm a bit surprised with Alexis' involvement they didn't anticipate the bot problem. Alexis left reddit several years ago but I'm sure he's still in touch with the folks who run the place. It would've been worth it to talk to them about the threats they currently face and how they deal with them.
v3 introduced proper nested comments and filtering, problem was they were slow to load but even worse was the design. Just very bloated and padded and the information density dropped through the floor.
Absolutely. They kinda brag about it now. But I think it was just the founders making multiple accounts. It sounds like the new Digg was worried about bots scaring people away from the site with thinly disguised ads.
