I meant to post this last week, but I was distracted by assignments. Ah well.
I started establishing my Personal Learning Network (PLN) via Twitter about a year ago, at LibraryCamp Perth, in 2010. The week before, I had done an assignment at uni that required me to use Twitter for a week (thank you @libsmatter!!!). I had intended to close my account after that, but seeing the way they used Twitter at LibraryCamp (particularly having the LiveStream projected behind the presenter), convinced me of how useful Twitter can be. As a result, that day I began to connect with other librarians, beginning my PLN.
