CRM tools to integrate social media intelligence

2009 will be the year where more and more businesses take a serious look at how they can make use of the intelligence found in social media platforms. Now salesforce.com, the leading online CRM software, is also looking at Twitter, and has included it into their Service Cloud offering, after also doing this for Facebook. Missing from the list so far are LinkedIn and XING, but as these professional contact lists will include more features to network (e.g.  what you are working on) this will change, I think.
