Thing #13 - What's all the Twitter About?

OK - I know I am old and behind and frustrated but I really don't get the whole Twitter thing! This is the third time I have been on Twitter and I cannot seem to find anyone. The 1 person who is following me (and I am following) is a colleague, which is fine, but I don't think she is tweeting much. I tried following Austin Public Library, because I wanted to see what kinds of things a library would tweet about. It was the stuff I would have expected, but there were probably 3-4 tweets a day. Do their patrons want that many messages from the library every day? I would be interested to know how they got their 97 followers and how many are patrons and how many are staff, etc.
