Mining Twitter Article (Not technical)

This is an interesting article http://isc.sans.edu/diary.html?storyid=5728 due to the fact that they have links that are interesting related to mining Twitter. It is a little outdated and a few of the links do not work but still semi-useful. Keep in mind data sets that were previously available, for example http://snap.stanford.edu/data/twitter7.html, are no longer available due to a Twitter request (read about it here). However you can still use the Twitter API to get data, you are just limited to the number of tweets you can get per day/session (can't remember). Also useful is this article.
