Peter Caputa is wondering about Furl or web archiving tools.
Spurl vs Furl: Not sure what came first, but there are not a lot of differences between these two. There are some differences in implementation: Furl has a toolbar and spurl uses a browser button for MS IE users. After a quick trial, I would say furl gets a better rating on usability. But, I have talked with the founder of Spurl, and he is definitely on the right track. And both of these tools allow people to archive single pages of content. So, instead of just storing the link to it, you can store the page. Like I said, I don`t use these tools. Does anyone? For what purpose?
As an active furl user, I would say that furl functions as a Social Bookmarking++ service. I use it the same way as most people use Del.icio.us with the added advantage that pages I bookmark are also saved. That includes the ability to share entries out in a complete feed or by category. Very handy. Additionally, the page categorization allows furl to "recommend" pages to me with startling accurancy. As far as what you can do with furl, checkout my Furl Bookmarklets for ways to traverse all the furled pages you are interested in. Also checkout 10 Cool Things To Do With Furl.
