The 30DC adwords strategy is very specifically as an extra testing method for researching a market, which is why you only worry about your main keyword phrase.

However, it is still a good method. The more keywords in each adgroup, the less targeted they are likely to be (you want your keywords to be highly targeted to the page you are directing them to). So, it makes sense to have many adgroups within each campaign, and each tightly focussed.

Certainly the days of piling hundreds of keywords into each group is long gone - Google will either charge you a fortune or turn your ads off altogether.
