Reminder to take community detection algorithms with a grain of salt. Here are three different algorithms, each with 2 or 3 different granularities. (Colors aren't consistent between graphs; just compare shapes the colors make) https://t.co/NuAq658kJ4

The real-world is of course communities within communities, but visualizing it is tough. Arguably, you have overlapping communities at each level of granularity! Even with similar granularities, algorithms disagree on where the boundaries are.

Nonetheless, there does appear to be some agreed upon structure. This seems like an ideal example of @Meaningness's nebulosity. Unsurprisingly, he was the one to bring up overlapping communities
