I quite like this blog entry, from the Society for Participatory Medicine, on how patients are using Twitter to "seek and speak out." Along with outlining how she used it during her bout with cancer ("I found information on just about every possible concern from ongoing clinical trials, to the latest medications, what foods to eat and why yoga was good for breast cancer patients"), the writer provides statistics, definitions, and guidance for the newbie Twitter user. A Twitter 101, if you will.
