In yet another attempt to get at the enormous backlog I have of sites worth , I’ve recently begin a regular feature called “The Week In Web 2.0.” It’ll be a short compilation of new decent sites that are worth noting, but maybe not necessarily worth a separate post…

Screencasting In The Classroom is a guide from Kathy Schrock (thanks to Vicki Davis for the tip). I’m adding it to The Best Tools For Making Screencasts.

Talky seems like a very easy video chat site where you can create private rooms. I’m adding it to The Best Online Tools For Real-Time Collaboration.

The famous Elf Yourself site is now up-and-running this year, where you can make free fun online holiday greetings starring you and others as elves. In the past they’ve let you grab images off the web to create the cards, but not this year. Now, you have to use your webcam or upload images from Facebook or your computer.

Tour Builder now makes it pretty easy to create your own custom tours on Google Earth. I’m adding it to The Best Resources For Google Earth Beginners Like Me.

Otter is a new tool for creating class websites. You can read more about it at Richard Byrne’s blog. I’m adding it to A Few Potentially Useful Tech Tools For Teacher/Parent Communication.
