I think the same. In the short-term, companies will be happy due to the cost savings, but as time progresses, if they aren't able to introduce the randomness of personal communication and interaction, the costs are going to mount up fast. I reckon that for many companies, they are going to see a reduction in some types of innovation.
Word of mouth plays a lot in promotion in any company. If a person is well known in their department only, and another is well know in theirs and in a couple others, the second stands a better chance of being promoted. In an on-line work environment I would imagine it is difficult to get that word of mouth contact.
It is difficult and it is easy to be caught in the bubbles - thinking one is more spread than reality.
