I’m really enjoying lemmy. I think we’ve got some growing pains in UI/UX and we’re missing some key features (like community migration and actual redundancy). But how are we going to collectively pay for this. I saw an (unverified) post that Reddit received 400M dollars from ads last year. Lemmy isn’t going to be free. Can someone with actual server experience chime in with some back of the napkin math on how expensive it would be if everyone migrated from Reddit?
Unfortunately, you can’t equate resource usage to number of users.
500 users will use more than 5 times the resources of 100 users, because activity feeds on activity. But it gets worse than being non-linear.
If you judge you’re using as many resources as you comfortably can at 500 users and close registrations, you will soon exceed your resource capacity anyway. Why? Because users who register elsewhere will increase your federation activity and therefore resource requirements.
