Hi,
The best part to social media is there are plenty of tools that you can work with, and many are free. If you are thinking of listening, you can easily start with Google Blog search, Twitter Search, and Face book Search. You can then progress to some really great tools. For analysis we use Radian 6 and Nielsen Online, but for day-to-day work we do use many free tools. On my iPhone I prefer Simply Tweet, but I like Seesmic on my Droid. On the iPad, I use Twit terrific.
