it is a deliberate attempt to outrank the sources.

Of course it is. That's like saying Obama's presidential campaign was a deliberate attempt to win the election.

The issue, though, is that Mahalo could not rank higher than original sources unless Google is doing a shoddy job of indexing the Web. Just because Mahalo has a few good pages doesn't mean the rest should automatically be trusted. Google need to figure that out - and fast.

This domain authority exploit is exactly what many business models are being built on...Demand Media, Mahalo, Aol, etc etc etc
