And as Twitter shows, it's not hard to offer both options and let users choose.

Twitter also implemented a timer so that, if you choose simple reverse chron, it forces you back into the ranking algorithm after a certain period of time.

Hmm, I wonder why they'd go to the trouble to do that? Maybe these social networks have motivations that override user experience?

FB isn't going to do anything that doesn't affect at least 30% of users. As always this is all about revenue.

I'm sure FB has done many, many things that affect less than 30% of users

OK name something they added that they actually kept in the current version of FB that is used by less than 30% of users in the life of their account and isn't there for regulatory reasons. They use way too much A/B testing for anything like that to survive longer than 2 years.
