There's a post by Melinda Gipson up on The Newspaper Association of America's Opportunopoly blog that explores NewsGator's new and growing relationship with mSpoke, which has been profiled before on this blog. You should definitely read the whole post, but here's a quote within the article from NewsGator's own Walker Fenton, about the power of related content widgets, which are made possible through our relationship with mSpoke:

"The more relevant the content, the more relevant can be the adjacent advertising.  When you compare related content ads with banner ads, we see significantly better engagement -- 3 percent to double-digit click-throughs, depending on where the ads are in relationship with the content recommendations"

If you're in the content syndication, related content, or contextual advertising arena, this article is a must-read.  Check out the full post here.
