First lady Michelle Obama is all the buzz here in San Francisco but she isn't the only celebrity talking about service and good works here today. Among the other high profile speakers conference goers will hear from are Maria Shriver and husband, California Gov. Arnold Schwarzenegger (who was a USA WEEKEND fitness columnist some years ago), plus rocker Jon Bon Jovi (at right) and actor Matthew McConaughey, who represent the Entertainment Industry Foundation, but who also have foundations of their own. Bon Jovi will play a set and McConaughey will introduce a video about EIF's plans for an unprecedented campaign using television shows and personalities we know well to promote volunteerism beginning in October. Stay tuned to the blog for more on that effort as they talk details.
