The UK’s web archive is pretty rubbish, therefore Iterasi (highlighted by TechCrunch) is a great addition to the web.
Rather than merely bookmarking a URL, you can archive the actual page, and can continue archiving the page on a regular basis if you so wish. The only downsides to the site are that it only allows you to archive on a daily basis (for the front pages of news sites you may want to archive more regularly), and it only archives when your computer, with its list of scheduled saves, is turned on.
The potential for webometric studies is obvious, it would seem as though even the most technologically incompetent of us can now simply collect longitudinal data. For example, Google searches may be collected on a daily basis to see how the results or the number of hits changes…and once you have archived a page, it’s very simple to then embed the page:
It also has potential for bloggers; when they discuss a page or story bloggers can now be sure that their readers will have access to the page that they saw rather than an updated version. How content providers will react to the archiving of their content is yet to be seen.
