Web 2.0

Well, now that Angie explained the title a little bit I think I understand Web 2.0 to mean that the web is finally something anyone can use... they can find things easily... and they can also contribute easily. In the past it was difficult to understand. There were lots of codes that you had to know in order to make a web page. Now there is no need for the average person to ever have to deal with the code in order to post something.
Also, I think the video was pointing out how much easier this makes communicating information. The beginning of the video (with the pencil writing and erasing) shows the "old way" of communicating which was time consuming and messy and then shows how easy it is to type and to change things as you go. No big deal.
How does Web 2.0 affect someone entering the workforce? They need to consider what they have placed on the internet that is a reflection on them (such as on a blog, on facebook, or on myspace). Now employers can easily do a search on the internet to find out things about prospective employees. But also it means that someone about to enter the workforce needs to be up to date on how to get around on the internet for email, research, and other such things. This may be an advantage for young people looking for jobs, in the sense that they are probably more familiar with this type of technology, having "grown up" with it.
Along these same lines, this could be a disadvantage for those already in the workforce if they are not familiar with it. However, it is also a benefit to current workers because it is making things easier for them.
In the midst of all the advantages of Web 2.0, the easy access and ease of use, there are other things to consider (or reconsider as the video puts it). We must always be making sure that things like copyright and privacy are being updated as technology advances. With more information being easier to get to (as well as personally put out there) there is a greater need to be aware of your own privacy. What do you want to make available for anyone and everyone? And what do you want to protect? What needs to be regulated in order to protect people from themselves?
Nothing is there that we don't put there... that is how the machine is us... and how the machine is using us. Without us, it ceases to grow, to change, to have any meaning. It is in our contributions and use that we express ourselves... the machine tells about who we are.
