I learned of the "mother of social media lists" and the "father of social media lists." Click here to see mom and here to see dad. These are the most comprehensive lists of examples of social media applications, videos, blogs, podcasts, widgets, crowdsourcing, bookmarking, microblogging, photosharing, wikis, mashups, brand monitoring ad nauseum. Check them out if you don't want to feel left out. (Thanks to Ray Schiel for showing me this list.)
