I’d like to see more outreach initiatives in posting Lemmy content to Reddit. Nobody not specifically looking for Lemmy is going to even be aware that it exists. Think about how many times the same posts hits #1 on /r/all. The API protest was massive and I would still guess that less than one percent of Redditors have even considered alternatives like kbin/lemmy exist.
I’m personally not worried about growing too much because instances can only get so big and still afford to be online. There’s no incentive to grow an instance beyond sustainability.
