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?

I would be wary.
When I started our main site I did use sub domain for the big categories like movies, world news, arts, tech etc. I thought it was a handy way to divide things up and even for users.
However, I did not realise some of the complication regards search engines looking at them as different sites and making stats hard to analyse sometimes.
Also it can encourage over-reach. We moved out of entertainment into all sorts of hard news and now two years later we have decided to slit that hard news off to a separate site.
Don't put all your eggs in one basket and read up on sub domains before you go down that route.

That strategy is already obsolete as Google is about to stop counting subdomains as separate domains.
In fact mass made for adsense sites are also old news so don't get your hopes up too much with this expert's plan from five years ago.

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.

Matt, suggest using subdirectories for small publisher [mattcutts.com...]
