chris has posted a chart showing the number of blog posts each day about the downing street memo since may 31st and comparing it with the daily number of news articles that mention the DSM. (chris actually got his data from PSoTD who explains that the news article count comes from google news and the blog count comes from technorati)
for some time there's a debate about how influential blogistan is on the outside world. i'm usually pretty skeptical of highfalutin' claims of how blogs are changing the world. while they have nudged news cycles a bit in the past few years, i really think their influence has been overhyped. anyway, this data at least suggests a correlation between blogistan noise and media noise. correlation doesn't necessarily mean cause. but on the other hand, i think it does mean something. and on the off chance it might work, i'm all for making noise.
