I tend to drop at least a line of adsense adlinks on a new site right from the first day.
I have two reasons for this:
Firstly (and most importantly, to me) it means I can track it in my Adsense reporting, which I look at least daily, with a standard report breaking down by domain (channel). This lets me keep my finger on the pulse of the site's growth without effort.
Secondly, it means I have always had some form of advertising on it, so I can't get whining later of 'you've gone all commercial man!' ;) because there has always been some sort of advertising on it.
