"One of the most popular posts of the week was the updated version of my blog post Seven Ways to Find Teachers on Twitter. I've heard from a number of people thanking me for the tips included in that guide. But if you're on Twitter and you want to expand your PLN (personal learning network) beyond Twitter, consider trying the tools and tips in my guide How to Build a PLN.
Both of these guides were originally published as Google Docs presentations, but I've also put them on DocStoc for those that would prefer a vertical-scroll presentation. Anyone is welcome to download, reuse, and remix these guides responsibly."
