Richard Byrne is the author of probably, in my opinion, the most useful technology blogs for teachers on the planet. I subscribe to his posts via Google Reader, and I am blown away on a DAILY basis by the resources he provides. The best thing about the resources he provides is that they are all free! What teacher can't use FREE resources? This Issuu publication is a collection of his favorite Web 2.0 resources from 2011 (so far). Take a moment and explore; I promise you won't be disappointed. Also, take a minute to visit his blog: http://www.freetech4teachers.com/... it will be time well spent!
