Instead, I believe it discourages more focused one-on-one relationship-building in favor of a bi-directional consumption model. People don't interact as much as publish and consume. Knowing what people are doing is not a real substitute for intimacy, but I think the dependence on FB as the medium tends to relegate people to the former (i.e. just keeping up).

In any case, I was responding specifically to an ancestor who stated that he/she was having trouble keeping in touch outside of FB. That makes my point: people tend to be so reliant on FB to manage their relationships, that those relationships evaporate sans FB to the point that people don't even communicate! But, of course, while on FB, people don't generally have meaningful, in-depth conversations.

That pretty much says it all, as it doesn't leave much space for real relationships. Not saying this is absolute, but that it is a net negative.
