Hide Aggregation from Google?

[meistermedia]

Google isn't a fan of aggregation, but sometimes it is a good way to fill out content when you cannot cover every news story there is. What I'm wondering is if anyone has continued to do any form of aggregation based on a category and hide that url from Google. Example:

example.com/industry-news/ -- is where you'd post aggregation stories but you block robots from crawling that.

We wouldn't be doing this for search value just value to our readers. Thoughts?
