Reporting in. Once you spend a bit of time here you will find the things you are familiar with in a different form, Lemmy has its own culture going. Though there are also a bunch of sub replacements, or at least very similar communities.
Though it is of course true that reddit was the internet culture place for a good decade, and that reverberates through to how people communicate, what humor and references they have and make, and so on.
Over time more and more people will migrate, and help to foster new communities here. The fediverse is still in its pioneering stage, so naturally the content is less varied than on reddit, and there are still the occasional technical issues to work out, but overall it’s been a fun two months here. I actually haven’t missed reddit much, just for the occasional ultra specific answer I am looking for.
