I got probably 50+ FB friends from work, the people I wouldn't call friends IRL. There's still some unhealthy obsession with the friend counts. When I used FB, I did the bi-annual purge, unfriended everyone I hadn't talked to in months. Got some weird reactions too! I agree with you, FB will likely implement/force the echo chambers in the end, the current open social network isn't working, and banning one side will lead to a massive loss of ad revenue.
