This is an attempt to explain my thoughts; yes an attempt because the base of social media in my thinkiing is rather unstable.Why do we build a strong presence in one place and then move over to a new platform to do the same again? Maybe we should never have left the first place? Moving to a new environment is inspiring while we don't know what awaits us. Does Buzz really take our work to the next level of conversational collaboration? Time will show.
