average life of a Web page is about a hundred days

Twitter is a rare case: it has arranged to archive all of its tweets at the Library of Congress.

Sometimes when you try to visit a Web page what you see is an error message: “Page Not Found.” This is known as “link rot,”

Instead of scribbling marks in the margins of printed papers, I opened each student’s paper in Google Docs, highlighted text and inserted comments to clarify my thoughts, and then turned on the screen recorder (Jing) to record my voice as I scrolled through the paper and pointed to items with my mouse. Right after recording, I uploaded the finished recording to Jing’s companion hosting site, and then I simply copied and pasted the link to the recording directly into the Google Doc.

After about four minutes, they began the next task, copying and pasting my reflection questions into the bottom of their docs, and then responding to those prompts as they reflected on their work and my feedback.

As I watched them, I couldn’t help but remember the way that I used to provide feedback. Students would receive their graded papers, flip past the comments I had scribbled in the margin, glance at the final grade, and then forget all about it.

Social bookmarking. When you save a Web site as a favorite or bookmark, it's added to a list that stays within that browser. Use another computer, and you don't have access to that bookmark. When you use a social-bookmarking service, you save your bookmarks on that server, making them available to you wherever you access the Web, and allowing you to share them with others. Ask your students to create accounts on a social-bookmarking service and to bookmark Web sites, news articles, and other resources relevant to the course you're teaching. Create a unique "tag" for your course and have your students use it, so that their bookmarks can be easily found. Ask students to apply multiple tags to the resources they bookmark, as a way to help them locate their bookmarks quickly and to prepare them for the kind of keyword searching they'll need to do when using library databases. If you're teaching a face-to-face or hybrid class, be sure to spend some class time having students share their latest finds, so they can see the connections between this work outside class and classroom discussions. Students most likely won't find this difficult. After all, you're asking them to surf the Web and tag pages they like. That's something they do via Facebook every day. By having them share course-related content with their peers in the class, however, you'll tap into their desires to be part of your course's learning community. And you might be surprised by the resources they find and share.

the noise is worse than ever. Indeed, it is being magnified every day as more people pile onto Twitter and Facebook and new apps yet to crest like Google Wave. The data stream is growing stronger, but so too is the danger of drowning in all that information.

the fact that Seesmic or TweetDeck or any of these apps can display 1,200 Tweets at once is not a feature, it’s a bug

if you think Twitter is noisy, wait until you see Google Wave, which doesn’t hide anything at all.  Imagine that Twhirl image below with a million dialog boxes on your screen, except you see as other people type in their messages and add new files and images to the conversation, all at once as it is happening.  It’s enough to make your brain explode.

FitWithFriends (FWF) should help students attending UVA achieve their fitness goals by motivating prospective gym goers through connecting them with potential workout buddies. FWF will provide guidance to new users in creating a profile and matching with another person through simple instructions. It will provide a service in which users can input information, such as fitness goals and availability. FWF will also provide a database that will educate users on how to use different equipment as well as supply different workouts. Next, users can match with a single user or a group, and if it is mutual, FWF should be able to connect them within a day of the match to plan workouts. FWF will handle various physical activities from running or weightlifting to rock climbing depending on user interests. FWF can also offer rewards to students who continue to complete workouts. FWF will work to build deeper connections between students through a medium other than academics.
