Great post about the power of Twitter. It is almost so commonplace as to be trite. But it isn't trite. It is a very real part of a good teacher's PLN. Better than a search engine, the people engine of a giving, helpful group of twitters. But remember that in order to Tweet and receive, you also have to share and receive. You get back far more than you give but you should give not just ask. In short, be there for your tweeps and your tweeps will be there for you.
