The TFPL blog has an interesting post on some comments from a focus group on Social Computing (and it's use in the workplace)

To draw out some specific comments/points:

• The Civil Service code for online participation
• Example of the reduction of email "burden" by use of a wiki
• A company responding (positively) to a negative 'Tweet' about them
• "IT must learn to trust people with tools and increase its user focus"
• How a tool is rolled out impacts on whether it increases or decreases workload
