This got me surprised:

"Mobilizon is designed so that you can follow the news of a group, but not of an individual : it is impossible to follow a single profile. In Mobilizon, profiles have no « wall », « thread » or « story » : only groups can publish posts. The goal is to get rid of the self-promotional reflexes where we stage our lives to be the person at the center of our followers. With Mobilizon, it is not the ego but the collective that counts."""

I understand the motivation but it leaves me with the strange sensation of exchanging one kind of centralization with another. It doesn't click with me.
