When you increase the size of a set, or a network, you increase its /cardinality/. Again: Mastodon's growth from 80k to 300k users in the past ten days.
What does /not/ change with scale is the ordinality. If you double the size of a network, there are still precisely ten "top ten" slots. But there's twice the competition for them, or twice as much content (assuming linear scaling) to be filtere to find that set.
And there are only 24 hours in a day.
