The New York Times reports that "Google researchers say they have a software technology intended to do for digital images on the Web what the company’s original PageRank software did for searches of Web pages." The algorithm, dubbed VisualRank, weighs and ranks images that look most similar.
WebmasterWorld members fear that this could be a problem for spammers -- just like folks aim to build links for PageRank, so too this may happen in the image arena.
However, it may build traffic to images too, which some individuals are hoping for.
Perhaps this is the beginning of greater software technologies that will "index audio spoken in videos" and podcasts. Those transcription services would be super cool.
