More than EPC, another factor to consider is if and when text ad blindness starts to creep in. Like the way of the banner whose CPM rose to statospheric heights at the start, then plummeted to the bottom a few years later. The more text ads the user sees, the greater the likelihood that they will learn to eventually ignore anything that has "Ads by Google" label on it - whether the publisher has camouflaged it to merge with the content or used eye catching colors.

Until then ... get on the bandwagon and enjoy it while it lasts. Then it's on to the next big thing, whatever that may be.
