PageRank is the unofficial, and official, and semi-official, arbiter of value on the web.
And it’s just deeply broken – not because there isn’t data that informs all of our collective rank. But because we have no idea what that data really is, or how it’s combined to determine value in the Google economy.
So please, Google, either give us more granularity, or just go dark and don’t tell us anything.
Oh, and please, Larry Page, just as a tenth anniversary present, can you pretty please make BackRub for real? I’d really love to have it. So would a lot of others, I suspect.
