more revenue by optimizing a site for adsense earnings

Google AdSense Secrets - Making More Money with Google AdSense
So I open my browser this morning and found a link to this guys site. I usually ignore sensational things like this, but I see Chris Pirillo is one of the happy customers. I've been reading Chris' lockergnome off and on for years. So if he is recommending something it probably works.

I've been running AdSense on this site for half a year now and it has helped pay all the hosting charges and any bandwidth overages if they occured.

If I could optimise this site a little more, maybe up the clickthrough's then I'd be able to review a bit more hardware with the extra money.

My weekend was spent backing up old data and photos to DVD-R disks as part of a long over due housekeeping chore. At the end of the job I'll have a stack of 30-40GB hard drives and one 250GB firewire external drive! I of course wouldn't need all that storage space if I hadn't bought a canon eos 20d camera. Best camera I ever bought!
