Twitter is always part of that answer.
For me Twitter is a huge resource of headlines, news stories, product reviews, lesson ideas, educational policy discussions, and in my opinion one of the best ways to curate & aggregate exactly the content you want to see.
It is also a great way to communicate with colleagues & parents as well as keep on the pulse of what my contemporaries are doing in their schools.
Feel free to follow me on Twitter. If joining Twitter is not your thing, my live feed is displayed here...
