Wow, Graham! Someone put in a lot of work and creativity into that site for no apparent reason or purpose.
I didn't click on every button or link, but do they do anything there to actually make a dollar (or a Yen considering where you are)?
.....OH, looking again, I see that some of those Amazon.com and poster sales links are real, Maybe they get some commission... I've sold about $1500 worth of stuff for Amazon from my book reviews site, and have yet to see a cent from them though....
