DESCRIPTION:The glut of information online has led to a scarcity of attent
 ion\; users need effective means to acquire and consume content. One simpl
 e content acquisition mechanism is pull support (users get to access what 
 they want from a catalogue). A second method is the automatic highlighting
  of popular content by websites. A third mode is social  publish-subscribe
  networks such as Twitter. A fourth\, recently emerged trend is explicit m
 anual curation of interesting content. \n\nThis talk will be a data- and u
 ser-study-driven exploration of these content acquisition models\, identif
 ying advantages and drawbacks\, and proposing potential fixes and improvem
 ents. In particular\, we will argue that broadcast-based push can sometime
 s be more efficient than pull\, that social networks can help highlight le
 ss popular niche-interest content which is often ignored otherwise\, that 
 efficient near real-time re-ranking is necessary (and feasible) for  high 
 volume publish-subscribe networks\, and that curation\, especially structu
 red curation\, by users with diverse interests and regular updates\, can u
 sefully complement other methods such as search.\n\nThis is based on work 
 published in AAAI ICWSM 2012\, IEEE/ASE Social Informatics 2012\, WWW 2013
 \, and AAAI ICWSM 2013.\n
