What do RSS readers and urinals have in common?

If you are a regular reader of the MIT Advertising Lab blog, you already know the answer. They are both locations for innovative advertising models. Most blogs tend to follow the crowd and the general buzz, but I never know what to expect when a new post from this unique blog appears in my RSS reader. My favorite post from the recent past was a plan to introduce heat activated urinal billboards or HAUB as they're known in the bathroom advertising industry. To return to the Internet theme of this blog, there have also been great posts on ads in RSS readers and Google Maps.
