We started with Zite which helps you find articles about topics you are interested. Zite has become one of my favorite tools and apps because I want to stay current on articles and news but don't find I have the time. With this site I can save the articles to EverNote and then go back and read them later. I also can access them later even if the article is not longer listed at the original location. I've been really happy with Zite and continue to use it alongside Twitter in my building my PLN.
Twitter which is a site I joined when I became and Ed Tech in August. I have been slowly easing myself into Twitter and it's uses. The past few months I have gained an appreciation for Twitter in gaining information regarding current trends in education, connecting with colleagues and other professionals, and sharing my opinions/current learning.
