When they work, they give you interesting info. For instance, I used to think, and most of my blogger friends told me, that my posts are way too long and nobody reads them because of that. I also tend to write long rambling sentences which is not blog etiquette.
Interestingly enough, in analytics, my most accessed posts are the longest ones (which should make the one below this one the most popular of all) and my least accessed is one where I simply said I had had a bad day :-).
hmmm, food for thought.
communication is essential to business making and it involves more than the ability to name your product, write a tag line or a press release. It's an intricate, rational and scalable effort and, let's face it, not anyone can do it.
