You've got to consider a couple of things:
1) Do the subdomains make sense? In other words, if you have one site on puppies, another on the life of Mother Teresa, and a third on municipal bonds, does it make sense to have them all under the domain "mysite.com"?
2) If mysite.com gets whacked in the search engines, won't the subdomains go down with it?
Finally, if your plan is to create a whole slew of sites or subdomains on a zillion topics that you know little or nothing about (as too many AdSense publishers do), are you prepared for the day when that strategy will no longer work?

Having multiple subdomains is fine when you have tens of ideas that could generate little, stable profit that would otherwise be decreased by the price of domain. Especially if we're talking about costly domains in some countries. If a domain proves successful, one should redirect the traffic from the subdomain to normal domain.
When you create subdomain it is crucial to make sure that your traffic also comes from sources other than search engines.
