Plaxo is a nice free site for maintaining one address book among any number of different media devices. This is done via nice web interface and updates address books automatically. This is very handy when trying to juggle multiple address books for either email or phone, etc.
Boom Writer is a very interesting new website for collaborative writing for students. This is done by having students follow up writing on a story that is already started by an accomplished author. The other chapters get voted on online and the winners get put into a book. The winners then get unveiled. This is free for schools and a great way to explore 21st century technology w/ students.
Protagonize is a cool site I just found out about from the wonderful blog of Larry Ferlazzo. Not only can users create collaborative stories (ie, Folding Story), they can also create choose your own adventure style books. This is very innovative and sets Protagonize apart from other similar sites.
Zondle is a new (beta) site for educational games that supports learning. There are tons of games to choose from in every subject area and the games can even be embedded into a site/blog.
Desmos is a cool new site for creating interactive content/lessons for education. This is done all through a browser and is collaborative by nature which makes it ideal for education (web 2.0). 
Flip Snack is a new (beta) site that I just found out about from the amazing, iLearn Technology. Flip Snack is a very nice looking site that reminds me a lot of Bookrix or Mixbook. All a user has to do is upload a PDF and then choose options on how they want their flipbook created. Once the book is created it can then be shared on your favorite social network or embedded into a site. The book can also be downloaded. The only other feature I'd to see is the ability to order a hard copy of your book like you can do on Mixbook.
Go Pileus is one of the easiest file sharing sites around. All a user has to do is drag-n-drop files from their desktop right in their browser window on the Pileus window and items are transferred. It also integrates w/ bit.ly for making URL's shorter.
Search Team is a site I just found out about from, Free Technology 4 Teachers. This is a search engine designed to work in teams as a real-time collaborative search engine. This works by a user saving their search and then sharing w/ others who can then refine the search. It is rather innovative and worth a look.
Beat Lab is a super fun site for creating and mixing audio. This is done by moving the cursor in different directions to draw a line and then listen to the music that is created by different instruments. Once the song is completed it can be saved and then shared either on Beat Lab or Facebook.
Spider Scribe is a new (beta) site for online mind mapping and brainstorming. Like other similar sites users can link many items such as: files, calendars, notes, etc. These maps can then be shared w/ others or made private.
Faceflow is a great site for creating a live video chat w/ up to 4 people. To start a chat just register and share the unique URL that is generated. As well as chatting a person has a screen for texting as well.
Present.me is new (beta) wonderful site for uploading powerpoint presentations then adding a narration. The finished product actually combines the two so you see the presentation and the narrator as well. When the presentation is done you can share it w/ others via a URL or embed into a site. If you upgrade your account you can then activate privacy options and others as well.
Zapaday is a new (alpha) site for getting news on the web. What makes Zapaday so special is it tries to bring you news of the future rather then current news. Here is a quote straight from their founder...
"A wiki (
i /ˈwɪki/ wik-ee) is a website that allows the creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor. (Wikipedia)" Wikis are used in a number of different areas for a number of different reasons, education being one of the most popular. The creation of a wiki not only allows users to engage in 21st Century Technology it also helps increase technology literacy.webdoc in action from webdoc on Vimeo.
A lot of press has been going around for Adobe Creative Suite 5.5 and for good reason. This is release from Adobe and has lots of features for the mobile learner as well as ISTE standard compliance. As w/ any Adobe product the latest in flash technology can be found as well as leading web authoring tools (ie. html 5).
InstaBlogg is a great site for creating a single blog post. It's very easy to use w/ some nice features such as making the post public/private and turning on/off comments.
