Microtargeting an audience—too bad meeting managers don't have the data the politicos have

This fascinating New York TImes article on how politicians can now "nanotarget" their marketing messages to very specific demographics based on all the data our credit card spending habits and Nielsen rated TV viewing gives them makes me marvel. While hopefully anyone who needs to market a meeting knows how important it is to craft different messages for the different groups of people coming to a conference, how many are really doing it? And to what depth? With the amount of data now available to meeting managers, it's inexcusable not to take advantage of it and speak to each segment of an audience in a way that, well, speaks to them.
