Using Twitter to find and disseminate ideas, lessons

I follow a history teacher, David Korfhage, who originally tweeted a link to the online program ThingLink, which allows you to tag images with video, audio, social profiles, and web links. Today, I went to his original post and replied, thanking him and including a link to a lesson I created using ThingLink. I created the lesson on Google Docs and shortened the Google Docs URL using Tiny URl. Within minutes about 12 people were viewing the document. You can go into Google docs and it shows other viewers.

This is all very cool and a wonderful way for teachers all over the country to find and share ideas, lessons, and thoughts.
