Many folks left Dig for their primary feed when they did the UI update. I think I switched over to Slashdot around that time. The multi selector for karma, on the comments and them changing usernames so my original no longer worked drove me to reddit as that prime feed for me, for about 10 or so years.

As reddit exploded... that main home switched to here. Not quite that same sense of community and always a grab bag of subject, so much closer to Digg/Slashdot feel. I never ended up doing facebook or some of the other social media sites. As reddit tried/tried to become that sort of space (with monetization!) it became something I was not looking for.
