Universal McCann published the 3rd Social Media Tracker, Wave .3 (warning: PDF Link!).
From the research it turns out that there are 8,1 millions of blog readers in Italy.
orangeek's blog has 102 readers per day (average from Google Analytics); 84,13% from those readers are italians (why the hell am I writing my blog in english???).
So, I can say that the 0,001059% of the 8,1 millions of italian blog readers will notice this post.
Definitely interesting.
