I've been trying it out for the last week. I have my own opinions, but I'd like to hear others and see if we have common ideas on what is good/bad/indifferent about the Lemmy ecosystem.
As much as I'd like it to be, it doesn't have the network effect/popularity that Reddit does. It covers maybe 70-80% of my Digg+ needs, but there are many topics/subs I want that Lemmy just doesn't have.
"Be the change you want to see" is always there: if a topic/sub doesn't exist, you can always create it yourself. But no good deed goes unpunished, so you're now the owner/moderator...
