Is the sandbox really a filter?

Google shows low inbound linkage, could this be a reason of "the sandbox"

From experience, Google shows about 10 percent or less of the amount of links you obtain. Take a look at microsoft.com. They have 144,000 links that Google shows, their new search engine already shows 3,000,000 links. Altavista shows 25,000,000 links.

Now some of you may say that Google just doesn't show pages that are pagerank 3 or less. That is not true because Google shows some links that are 3 or less that I link to. So scratch that.

Some may say, Google may just not be showing all links, period. Well then what links does Google show, and what links do they decide not to show? Obviously it can't be that they just don't show pagerank "3 or below sites" that link to you, because I just disproved that. If they are picking and choosing only what they want you to see, does it mean they have applied an algorithm to only show 5 to 10 percent of the links that you obtain? Furthmore, how does the algorithm know which links out of those 5 or 10 percent to show? What reason would there be to not show the correct amount of links? Could it be that the number of links Google shows really is that number that it recognizes? hmmm.

The new MSN beta search shows that I have about 400 inbound links, google shows 24. I rank better in MSN beta, and perhaps this is the reason why, just like some of you probably are ranking better. It seems that google takes forever to recognize new links, and on top of that, it seems to ignore a great deal of links that you obtain.

Could this be a partial explanation of what the "sandbox" is....Google being very slow at finding new links and as a result, poor rankings?
