We've been using Radian6 as a Social Media Analytics tool for some time and I wanted to share the differentiators in their tool vs others that our clients seem to like so much.
1. Time to discovery - results are FAST! Usually real-time or max 30 min for a really broad query.
2. Ability to drill down in queries - in other words you can do a search within a search. This is really valuable in being able to drill down into very specific things you want to know.
3. Ability to pull top results in different ways - those of you who have pulled down a mass of comments in an analytics tool can appreciate how valuable it is to be able to bubble to the top and prioritize results... by Top 10 or by Twitter users, etc.
Radian6 put out this video to announce that they have some new product features coming out - you gotta love a company where the VP of Marketing does a decent Johnny Cash imitation! Looking forward to seeing the new features guys!
