If you love English, vote in the Macmillan Dictionary Love English Awards for the best websites and blogs about English. You can also check out last year's winners, and those from 2011.
A few highlights from the past few years: printables, wordsmith, worldwidewords, filmenglish, and closeyourtextbooks. I can't wait to try some of these ideas out in my classroom next semester.
And of course, my all time favorite: Free Rice, which helps people learn vocabulary and gives rice to people who are hungry.
