How BT uses Social Media Tools

Richard Dennison just shared a case study that was done for BT on how they use social media. If you follow Richard's blog you won't read anything new, but this case study does sum it all up nicely.
What I was wondering though is: Do they help their users/customers decide where to share and store information? With all these tools, it can become hard for them to choose the right tool! I’m working on an internal document to do just this. And I’ll share it with you soon.
