Wow, sounds like I need to get up to speed on twitter! Fortunately I'm already a pinterest junkie :) Love the youtube idea, too. Thanks for all the info.
As far as building up circles, I'm not really sure how to do that... I've included lots of people in my circle, but don't I have to wait for them to include me in theirs? I know, I know, such a newbie am I!
Thanks again for the help :) Will help you out in any way I can, too!
