Researchers at HP Labs created the Blog Epidemic Analyzer to track how ideas spread through blogs. They’ve found that the most popular blogs just pick up on ideas from lesser known blogs, often without giving credit. This is another perfect example of Malcolm Galdwell’s idea of social epidemics from The Tipping Point. (See my original
review of the The Tipping Point.) Ideas spread through society, or through the web, from experts (who find the info) to networkers (who distribute them widely).
Speaking of giving credit, I
read about this on Wired. I was orginally pointed to Wired from Slashdot, another blog.
