neveremail - I havent seen a difference whether I develop the domain the day I buy it or if I wait - it works exactly the same and has for years as Bill stated
Bill - as far as language in the patent - Ill look around to see if I can find any and get back
As far as Jil - that kind of "garbage writing" is meant for the masses - I could have said the same by saying that Google uses all kinds of algorithmic tactics on a newly purchased domain that makes it difficult for someone that wants to spam with a domain and makes them wait a while
My opinion as I stated before is that there is no delay with a fresh domain - with a previously owned domain there are some hurdles to overcome to make sure that you arent going to try to benefit from a domains previous attributes. Which again has been around since the "DMOZ expired" buying craze and was a defensive move that Google saw a need for - otherwise a domain takes just as long to get in and rank as it always has.
