They work by users marking their posts with the appropriate hashtag so the other users can easily follow what’s happening. Twitterers talking about things in the realm of education/technology will often use the #edtech tag. The neat part is that someone doesn’t even need to have an account to follow the action. Try it here http://search.twitter.com/search?q=%23edtech. Currently there is a lot of noise regarding people joining certain groups such as the ed tech twitter group, and registering at wefollow, but if you sort through it you can find some good resources, tips, etc…

Thinking of joining twitter? You won’t be alone. You can start by getting an account and adding @teachertechblog. Then you can visit wefollow.com and add some of the top ranks for the #edtech group. By then you should be well on your way to a timeline full of… stuff… hopefully good resources and the like.

If you search for education or e-learning in their search box you will find a small selection of general apps that can be used in Education, but I think the power here is the usefulness for nitch groups like design, art, and music. Over the next couple of weeks you’ll probably see a few of these featured. Feel free to share how you’re using them in your classroom though.
