I follow a few blogs as well as this site. I am on Facebook but mainly to keep track of family and friends, not for scrapbooking. I do get Creating Keepsakes too. Any more would be information overload.
Mainly blogs for me. I have some of my fave manufacturers on my facebook just so I don't have to bother having them on my faves. I sign up for newsletters when there's something to win by signing up. Then I unsign myself a little later.
