And now a word from our blogger.
Marqui Product Placement in Blogs
[Marc Canter] sees the program as a good alternative to the automated ad services offered to bloggers by many online advertising networks. "I hate the idea of having an ad on my page. I like employing humans to think," he said.
About whether that entry is an ad or not. I like thinking about important things and not wasting my thought and time on discerning the blogger's agenda, don't you?
In Rotting Media they call this a "disclaimer." They also make it pretty obvious which are the ads and which are the stories.
