spam, we all hate it. In fact a whole industry has been created around preventing it, blocking it and managing it. There have even been laws passed to try and control it.

What about the other 10,000+ marketing messages we are bombarded with everyday, billboards, magazine ads, radio, TV, websites, blogs, podcasts, it is un-escapable.

Why don't we put in the same energy to ward off all these other intrusions into our cranium? Is it because we have experienced some of them longer?

What do you think?
