The document discusses three social media platforms - Facebook, Twitter, and blogging - and provides guidance on how to use them for extension work. Facebook allows users to create profiles, connect with others, and share posts, photos and events. It offers privacy controls and options for pages, groups and networks. Twitter allows microblogging through tweets (limited to 140 characters) and includes features like replies, direct messages, retweets and lists. Blogs are online journals that allow for longer form posts with photos, videos and links. The document provides tips on setting up accounts and pages as well as examples of how extension agents currently use each platform.
