Flashbacks to the first hour using reddit as an former digg user...
It's fine. If people want to switch they will do so.
What separates the smart from the stupid is not the ability to adapt to something new, it's the ability to overcome obstacles they may encounter when trying the new thing.
IMO the one thing that should be possible to do on lemmy is for users from one server to be able to post and comment on another server within the lemmy network.
Posts and comment made by users from a different realm could be published as some variaton of "user@server", that way we could have multiple instances of "user" on the network, just on different servers.
Lemmy looks great, I hope it manages to comes out on top on the upcomming battle of the reddit alternatives because due to it's decentralized nature it's pretty much impossible for lemmy to go south like reddit and digg.
