If i’m understanding the last graph right, it’s showing the total number of active monthly users per instance’s top communities, filtered by the overall top 100 communities?

So if an instance has activity spread out over many niche communities, that activity isn’t represented on this graph?

I would think having a diversity of smaller communities is more in-line with the spirit of the fediverse, I’m not sure of the value in slicing the data in this way.
