I like that you can see what you're doing vs. your competitors vs. the industry as a whole. You can break break analysis at a very fine detail (looking at your own social performance, how your campaigns fared) and quickly reference what's working and not working for other companies.
The new attribution feature on the Content Feed is a really nice addition to the insight you can gain. Since it's pulling from Google Analytics, i don't have to check that or our CMS separately and can see how engaging the blog was, and how many views it actually got.
