Interesting. A few obvious mistakes like English Harbour and Playtech in there LOL but quite clever. Although for me, I'm starting to get quite wary of Google. I can see in time they have positioned themselves to start competing with webmasters.
If the Yahoo/Bing thing fails to gain market share then we're not far from a monopoly situation. I read recently they already started to do this in the Travel sector through partnership deals. That's only a small step away from affiliating.
That is pretty cool. Wasn't it called Google Sets a few years back? I remember seeing somthing similar in their labs years ago, just without the GridView.
If I look at that link I scroll down and see the actual Nostalgia Casino website there which has a new bonus.. Old bonus is showing.. so not specifically affiliate sites.. even the actual casino websites are showing incorrect bonuses on that tool.. i wonder how often its updated.
