Pinterest just like an online bulletin board. You can 'pin' useful pictures, infographics, videos or documents to 'boards' based on category. Well, it just like what I did with my own pinterest on http://pinterest.com/fitfun2012/ . So far, I make 13 categories for my boards, they are Writing, ICT, English Language Teacher, Vocabulary, Grammar, Pronunciation, Speaking, Education, Poem, Environment, Students and Movies. And this is my two favorite boards : Writing and Grammar. So,if you have same interest with me you can visit my Pinterest here http://pinterest.com/fitfun2012/.
