Another extension to this are the ads found on Techmeme. They basically charge 6k per month and it shows the companies most recent blog post as if it were a Techmeme article. FYI, they are CLEARLY designated as sponsored posts. They are the only ads I have ever clicked, looked at, and most importantly remember. It seems Digg is sort of doing the same thing here. Curious to see where else and how else this could play out.
