37signals Takes a Whack at Google
37signals provides 37BetterGoogle. Yes, the folks at 37signals who focus on building more usable interfaces through simple design, have takn a whack at improving the Goolge interface. 37signals provides a brief discussion of their added alternate search elements that can help aid the user more easily find that which they were seeking.
In a sense the interface modification offers similar searches to the user. This falls directly in to the information foraging direction of providing the user other attraction points that may get the user closer to the exact information that desire. The Google search may be returning information that is very close to what they are seeking, but a minor tweak of the search can provide more direct results.
This seems to be much like offering the user breadcrumbs. As most of us are aware not all users come to a site through the top level page. In fact you will most likely find less than half of the users of a site come in through the front door. Tools like Google give the user a means to get to the information they desire more quickly and easily. But, when a user comes to your site through a search they may not have dropped into the exact information they are seeking. It is up the the site owners to provide access points to similar information or information that is up one level (as often an external search will dump a user into a detail page of a site because of how search tool's weigh various pieces of content). Breadcrumbs on a page will provide the user with the ability to get to a page that may link to other related detailed pages.
