I was listening to DaveN and Mikkel de Mib on their show for WebmasterRadio, and the topic of the sandbox came up. DaveN said something along the lines of; "Yes there is a sandbox, but it is a biproduct of an attempt to do something else with the Google algo." Mikkel backed him up saying that Google would only really see the effect of any changes they made once it had been implemented fully and / or with a new crawl. I for one would listen to what they both have to say. But my questions is this, if the sandbox was some sort of freak accident then what were they actually atempting to do?
