An interesting discussion has emerged on the Cre8asite Forums about what webmasters and SEOs alike would do if Google were to get rid of that "little green bar" (since it really causes so much frustration).
Most of the folks are enthusiastic about the idea. But there is one decent application of PageRank from what I've read:
The only thing I use the green bar for is when I get a request for a link exchange I want to know if the bar is green or gray. If it is gray then I look to see if it is a new site that has not been indexed or is it a site that has been banned. Personally I like it for this one reason.
Others are looking for something else instead. Moderator Barry Welford, for example, would like Google to specify how many pages are in the supplemental index versus Google's regular web index as a RegRank:
RegRank = No. of web pages from domain in regular Google index / Total no. of web pages from domain as indexed in both the regular and supplemental indices
However, others aren't too sure that Google will ever go for such an idea.
What would you do if the green pixels were gone? Forum discussion continues at Cre8asite Forums.
