I referred earlier to Bersin's new report on social networking and a little while ago, I attended their new principal analyst, David Mallon's webinar on the report.
Bersin's research contains a good overview of social networking tools / providers and of their variety. As Josh Bersin explains on his blog:
- Consulting - Research - Speaking - Training - Writing
- Strategy - Team development - Web 2.0 - Change
- Contact me to create more value for your business
