Way back when, Larry Page thought it would be a cool idea to know what sites were linking back to any particular page you might be on while browsing the Internet.
In order to scratch that itch, he had to build a graph of the web. That graph became BackRub. But the product never became anything. Instead, he and Sergey realized that the index they had created was an excellent search engine.
That engine became Google.
But….I still want BackRub.
Really, wouldn’t it be cool to know who was linking to any particular page you were on? Why isn’t anyone making this available as widget? Anyone know of anybody doing it?
