Biggest problems I see with Lemmy right now is servers going down, defederation for petty reasons, and duplicated communities fracturing a user base. I’ve also noticed users with the same name on different instances but it’s not always clear if that’s the same user or a clone. i basically quit Reddit cold Turkey when I lost use of Apollo and I’d been there since well before the Digg migration. I’m looking forward to seeing how the Lemmy community resolves the issues I noted, no doubt they will.
