I would like to share my activities on Facebook.
Answer on How can I connect my Yahoo! Answers with my Facebook?
Go to your Yahoo Pulse page to easily do that:
Check under "Settings" (top right) > "Linked Accounts".
But please think carefully about this. You will not only be sharing what you ASK, but what you answer - and the information THAT person has posted, along with the other answers. That is a lot of info going out there for the world to see. The long-range impact of this down the road is something you need to really think about. Do you want future employers to see your activity here? Or your current one? Think about how many folks have been fired for what they posted to Facebook.
