Last night I implemented on TechSpot a new format of unobstrusive advertising called IntelliTXT, it's likely you have seen it in action before at other sites such as Anandtech. Using the wonders of DHTML, content pages are automatically spidered and links are created on relevant text keywords, these links are highlighted and underlined different than normal links, they are not displayed in big quantities and although the program is based on a per-click basis, you can learn what the advertisement is about before clicking on them - a tooltip is displayed.
It should be an interesting ride and we are counting with your support for making a bigger, better TechSpot.
