Can't see the sandbox being a "real" problem, or a problem at all. It's there to stop the SPAM. If I start a new company called Mesothelioma Lawyers Ltd you reckon I should show up in the top 500 purely because that's my company name?
Sure, the "sandbox", whatever it is, hurts some. It hurts people who are creating sites for free traffic. Many of them are spammers/freeloaders. It also hurts others. They - particularly anyone starting a new business with a business plan that relies on free SE traffic - are probably better off staying unemployed (or employed if they can find a job). Any new site starting off on the premise that free traffic will sustain it deserves to fail.
So, if you remove the sandbox as a reasonable cause for complaint, and remove most of the other whining, we'd reduce this thread to one page and those that can't even be bothered to read it will get a personal reply from Googleguy because he owes them.
