Free Technology For Teachers, written by Richard Byrne, is just about everybody’s favorite ed tech blog.
You can read it through many different avenues, but if you subscribe to it with an RSS Reader, there might be a problem that requires you to re-subscribe (there’s not a problem if you read it a different way).
You can read about the technical snafu and how to easily get back on track at Richard’s post, RSS Subscribers – I Need Your Help. You can easily fix it and not miss a post. And, trust me, you don’t want to miss a single post he publishes!
