"I got suckered recently (a subject for another post) into a cheesemo teleseminar on media trends. In it, one of the brilliant speakers proclaimed with confidence that the world's media still operate within a 24-hour news cycle. Heh? What world is that? It ain't mine jack....in mine, the news cycle takes 90 seconds:
+1 second to hit publish
+2 seconds for a blog to refresh
+3 seconds for feed readers to update
+4 seconds to email, link, tag, rank, or rate a blog post
+5 seconds for readers to form an opinion and/or leave a comment
+1 minute for Technorati to register a server ping, crawl and index a blog post
+8 seconds for alerts, watchlists and saved searches to propagate
+4 seconds for a blog post to plateau, amplify or disappear
+2 seconds for this cycle to repeat from the beginning
+1 second to realize the world's changing... "

I specially like the 'Update' - a comment to somebody claiming that the 24-hour news cycle would still be valid:
"In a 24-hour news cycle there are a total of 960 unique, 90-second news cycles."
