I love Richard Byrne's Free Tech 4 Teachers blog. He has so many amazing ideas and uses for free web tools. I don't always have time to read his blog, but I follow him on Twitter just to keep up.
He touches on everything--from Google tools to sites teacher can use to create videos to cool timeline sites. I can't even touch on the whole of his blog. I must admit, I've even used it to help me with this blog--I've learned a thing or two (or three or four) from it.
Check out the site and see if you agree with me. I bet you come away from it with at least one new idea you can use right away. And I bet you'll be back to see what else Richard shares with us!
