With whom do you want to share rumors, a blabbermouth or a person of few words?

EG10922 - On a social network, it seems better to transfer information preferentially toward those who have many social links ("blabbermouths") because they have larger impact on the network.  However, at the same time they can be bottlenecks for spreading information since information tends to concentrate on these blabbermouths and becomes redundant.  This paper shows that to achieve a faster spread over the network, it is indeed better to spread information preferentially toward those who have few social links (reverse preferential).
