Take a snapshot of any webpage, and watch it change This is a nice simple idea. Just give the resource the URL of a page and it will take a snapshot of it for you. You can then view the page and see how it changes over time. They'll send you an email to alert you to any changes. It's a little bit like the Wayback Machine aka Internet Archive but tailored to individuals. It's very new and still in beta, so open to change and development. Not sure that I would want to be emailed all the time - if I did a snapshot of say, a Google search for my name, that page will regularly change, and I don't want to be forever getting emails. I'd rather go back and revisit the link myself on my terms. Second concern is that when I looked through the list of frozen pages there were a few pornographic ones in the list. That they're porn isn't an issue for me - that I don't have an option to block them is. This makes the tool one that I instantly would feel unhappy using on a course or with children for example.
Hopefully these are issues that can be addressed as the resource develops, since it could be a nice little tool.
