This SocialWebCafe Twitter Event is about Facebook: Understanding Personal Profiles versus Fan Pages.
Even after Facebook has been around for awhile, and especially with all of the changes over its lifetime, there remains some level of confusion for people, on the difference between the profile and the fan page. Add in the groups and lists, and it can become interesting.
If you are a Facebook expert and you have a handle on this, please come share. If you are one of those who would like a better understanding of the differences and how to use the profile and page in a more effective manner, join us!
