Matt Haughey created a very informative piece on using Googles Adsense. I might at some stage in the future use AdSense for another project but I don’t think a personal blog would make anything from Ads and plus Google won’t do personal websites.
The domain name Matt uses is cool too – http://a.wholelottanothing.org , he is also the dude behind MetaFilter which I view a good few times a day.
