Social media can differ from our reading because it isnt all good or all bad, like the reading makes it seem. Twitter is fun to do because it makes you feel like people care about what your doing, even though they really dont. Haha. Myspace isnt as popular as it used to be im guessing because no one even uses it anymore. Facebook is checked before im or email by most people.
Twitter may be microblogging i am assuming and as the book said it is very discouraging for new users, but if they get past that initial few days and get some followers it becomes fun. However it isnt always about what you are doing or thinking about, lately there's a bunch of tagged posts on twitter and thats usually what you see in the news feed.
