The links that were given were Diigo.com or Delicious.com. I tried out Delicious.com, because I just liked the name, sounded cute. but the way I archive is by using bookmarks and sometimes copy and pasting URLs into wordpad or word document and then save in a USB just in case, mostly matters of the importance of the document/file. I would also save it in my email account or print it out and save a live evidence, again mattering what I am trying to archive. If its a normal website that I do not want to forget then I would bookmark it.
