Google Ads out of curiosity

Ads are often given as a projected revenue stream for some websites. It seems to me that this relies on there being sites which make money getting custom from sites which generate content. It would be pleasing if this model was self sustaining. In an effort to see if it works I am putting Google's AdSense onto my site for a bit, mainly to get a feel for the numbers.

It would be far more profitable no doubt for me to place ads for my own projects but that somehow seems wrong. Hopefully the Google ads will blend in nicely, whereas if there was any chance of making money I might be tempted to go for primary colours.

I have a sneaking suspicion that I am not allowed to reveal ad revenue as per Googles T&Cs but time will tell. Perhaps I can channel all ad revenue into ads for my own site?
