We have made some changes to the speaker lineup for IZEAFest. Arleen Anderson will no longer be joining us for the session on Twitter. I am pleased to announce that Sarah Evans (@prsarahevans) will be filling the spot. Sarah initiated and moderates #journchat, the top-trending weekly live chat between PR professionals, journalists and bloggers on Twitter. She is a guest writer for Mashable, one of the most popular technology blogs, runs her own blog PRsarahevans.com.
