"""The expectation of chronologicality"" (yes, a word, & also see http://jerz.setonhill.edu/EL227/2009/07/chronic-chronologicality/ ) 
 The curious thing is that ITN items already are not chronological. The nomination process ensures that they appear in the order in which they were nominated (usually only after they appear in a major news source) to be posted after they are approved, which frequently results in ITN items being badly out of temporal order. One interesting very recent example was the HIV 100 years old item ... which actually appeared originally in a fairly solid Nature study in 2008 http://www.nature.com/nature/journal/v455/n7213/full/455605a.html . (Disclaimer: I happened to have been following that one before it became imminently relevant to Ebola. http://www.livinghealthy360.com/index.php/how-old-is-hiv-28281/ ) So unknown to the reader, the reader's expectation of chronologicality is actually undermined by ITN's approach. - Tenebris
