Social media measurement and evaluation - after the event

I just read an interesting post by Jason Falls about a new product from Scout Labs providing online media monitoring and measurement. I was talking with someone at yesterdays Measurement Camp about these types of service and it seems to be a shame it is not possible to offer an after the event service, as it is my understanding that one needs to set something up before coverage appears (please correct me if I am wrong).

I have a client who has just finished a campaign which seems to have got 150+ online media clips and it would be very interesting to present in tamden some sort of social media specific measurement. This connects with another posting I want to do on yesterdays Measurement Camp, which I will try and do later.
