As Niel Bowerman commented there, profiles bases sometime do evolve into monoliths. The ever-growing list of things you can do on Facebook is an example, although that’s partly because Facebook is a platform for independent applications; in the same way, people can build independent applications either on top of the Profiles or leveraging them somewhere else, through .impact.
People may also be interested in Ozzie Gooen’s discussion document on the Advantages and Disadvantages of a Monolith Application. I’m conscious of the disadvantages, and am a believer in decentralisation.
