Wikipedia isn’t a social platform. I suspect that their text growth was log(n)
or something of the like. The only new text are things that are literally new or updates.
Lemmy has no cap there. The amount of new text will grow in some proportion to the user base. The more users and more instances, the more text. To say nothing of duplication from cross posting when you get wonky cuts in the federation connections.
None of this is free and it’s going to be a problem if Lemmy grows.
You can make a federated link by going !canvas@toast.ooo rather than posting the link, makes it much easier for users to join from LW!
