It's an interesting experiment, but is that realistic? It sounds like the test account just followed the first n things recommended, then the next n, then the next. Sort of like the game where one clicks the first link in the wikipedia article and ends up at philosophy.

Any real user doesnt follow random links, but ones he/she is interested in.

Its not like facebook has a monopoly--users would leave if they were genuinely dissatisfied.
