Tags are key words used to organize information. They're like the ingredients on a label. Hashtags - the tag prefaced with # - are used to aggregate information from different people. This presentation showcases some of our favorites. You are welcome to adapt and reuse with the attribution-sharealike license. We welcome your interaction -- comments, questions, suggestions, shares, clips, favorites, likes and hearts. Wiki http://planeta.wikispaces.com/tags http://planeta.wikispaces.com/twitter
