"Did you know that your tweets have an expiration date on them? While they never really disappear from your own Twitter stream, they become unsearchable in only a matter of days. At first, Twitter held onto your tweets for around a month, but as the service grew more popular, this "date limit" has dramatically shortened. According to Twitter's search documentation, the current date limit on the search index is "around 1.5 weeks but is dynamic and subject to shrink as the number of tweets per day continues to grow."

So what is the purpose of this site? It's simple. We want to share how technology with people quickly. Each video on the site will be under ten minutes. This is about the same length as my attention span and perfect for showing at the end of a staff meeting. Of course there are some sites like this out there already and we will link to similar sites on the homepage.We may end up having a few different videos on a topic e.g. Beginner's guide to Twitter and Advanced use of Twitter, but generally it will be short and simple. Anyone can upload a video, and you can do this in two ways. Either create a video and upload it to Youtube, Vimeo, Viddler etc and send me the link or email me and I'll give you access to add it to the blog yourself. It all depends on your level of WordPress knowledge really. Obviously some schools have some of these sites banned, so we will try and embed a video from one site and provide a link to others too. To make a video you will need either some screen capture software such as Camtasia or Jing or just use a webcam or video camera. You could be out and about filming, it doesn't need to be a video of a computer screen. the videos can be for 'free' software or for paid-for content, however…they can not be a sales pitch. If I deem the video to be more of an advert than a how-to guide, I will remove it. It should focus on how the software works and how it can be applied in the classroom. You may use these videos wherever you like, in a staff meeting or when working with teachers etc but please just leave us a comment to let us know that they were useful.

"Last week my wife and I told our 13-year-old daughter she could join Facebook. Within a few hours she had accumulated 171 friends, and I felt a little as if I had passed my child a pipe of crystal meth. I don't mean to be a spoilsport, and I don't think I'm a Luddite. I edit a newspaper that has embraced new media with creative, prizewinning gusto. I get that the Web reaches and engages a vast, global audience, that it invites participation and facilitates - up to a point - newsgathering. But before we succumb to digital idolatry, we should consider that innovation often comes at a price. And sometimes I wonder if the price is a piece of ourselves. "

"Wasn't it just the other day that teachers confiscated cellphones and principals warned about oversharing on MySpace? Now, Erin Olson, an English teacher in Sioux Rapids, Iowa, is among a small but growing cadre of educators trying to exploit Twitter-like technology to enhance classroom discussion. Last Friday, as some of her 11th graders read aloud from a poem called "To the Lady," which ponders why bystanders do not intervene to stop injustice, others kept up a running commentary on their laptops.

SearchTeam is a collaborative search engine. You start your research by creating a SearchSpace on a topic of interest. From within a SearchSpace, you can search the Web, videos, images, books and more. You can find and save only what you want while you are searching and throw away what you don't want or find irrelevant. You can automatically organize what you save, into folders of your choosing. Everything is automatically saved into your personal account, and you can return to your searches any time and continue from where you left before. What makes SearchTeam unique and valuable is that you can do your searches collaboratively with others you trust, such as friends, colleagues and family members. You can invite any set of people you trust to search with you from within a SearchSpace. An invitation is sent via email to those people you invite to join your search. When they enter your SearchSpace, they see exactly what you've found and saved so far. They can comment on or like your findings. They can chat with you from within the SearchSpace, and do further searches relevant to that topic and save more results into the SearchSpace. All changes made by any collaborator are relayed to all other collaborators in real-time, so everyone is instantly in synch with what others are doing. In addition to finding and saving search results, SearchTeam goes further to enable you to enrich your SearchSpace with knowledge that may come from other sources. You can upload documents to a SearchSpace to share your relevant reports / presentations etc. You can also add links to Web resources that you may have received from others via email or social networks. You can even create new posts to share your knowledge on the topic directly inside the SearchSpace. Together, as a team, you can leverage the collective effort to find good quality information, and benefit from the collective knowledge on any topic efficiently. In effect, SearchTeam is traditional Web searching + Wiki-like editi

"Last week, I read this interesting blog post from Kevin McLaughlin Entitled "Switching off the interactive whiteboard for good". It revisited the argument that IWBs have been a huge waste of taxpayers money, and should be replaced with alternative technologies. The post generated a large number of comments, and even caused Kevin to go over his bandwidth allocation, reminding me of an earlier IWB-related post to this blog, which remains to this day my most commented upon blog post ever! Matthew Pearson then posted a robust defence of IWBs, which again provoked debate in the comments and on Twitter - including the (rather amusing) retitling of Matt's post as "Interactive Whiteboards Are Awesome, It's Just People That Suck"."

By now, we're used to letting Facebook and Twitter capture our social lives on the web -- building a "social layer" on top of the real world. At TEDxBoston, Seth Priebatsch looks at the next layer in progress: the "game layer," a pervasive net of behavior-steering game dynamics that will reshape education and commerce.

"Companies who want to know more about prospective employees can learn a lot by checking their Facebook profiles, according to a new study. Jennifer Golbeck and colleagues at the University of Maryland surveyed the public profiles of nearly 300 Facebook users for information about their favourite activities, TV shows, movies, music, books, quotes, and membership in political or other organisations. They also looked at the "About Me" and "blurb" sections. The work did not include status updates or other data that is only available to users' online friends."

"The reality is the power of social media is enormous. It's what students are using to make a difference, our president used to get elected, and what Egypt used to start a revolution. Educators must get over their fears lest they make themselves irrelevant and leave their students unprepared. As I shared in my post Being Safe Online Is Being Safe In Life, the lesson is this. It's not primarily having a social networking profile, or giving out personal information that puts kids at risk. What puts kids in danger is being willing to talk about sex online with strangers or having a pattern of multiple risky activities on the web like going to sex sites and chat rooms, meeting lots of people there, kind of behaving in what we call like an internet daredevil. As the post is titled, the rules for being safe online are really just the rules for being safe in life. "

"So you and your students use the Internet everyday, but are you fluent in its language? Perhaps you've found yourself listening to a "techy" conversation where the terms IP, DNS, or PHP were being used and you wanted to know what those terms mean. What is an IP address? What is a DNS record? And just who is in charge of the Internet? Get answers to those questions and many more in Make Use Of's free ebook How the Internet Works."
