What is The Sandbox Effect?

The Sandbox Effect is: 

From Wikipedia, the free encyclopedia

The Sandbox (a.k.a. Sandboxing or the sandbox effect or the Google penalty) is a name given to an observation about the way Google ranks web pages in its index. It is the subject of much debate—its existence has been written about^[1][2] but not confirmed and several observers state that they have observed the contrary.^[3]
According to the sandbox effect, Google temporarily reduces the page rank of new domains, placing them into what is referred to as its "sandbox", in an effort to counter the ways that search engine optimizers attempt to manipulate Google's page ranking by creating lots of inbound links to a new web site from other web sites that they own.
A "reverse sandbox" effect is also claimed to exist, whereby new pages with good content, but without inbound links, are temporarily increased in rank—much like the "New Releases" in a book store are displayed more prominently—to encourage organic building of the World Wide Web.^[3][4]

OK, I know that, but what is it really?

The Sandbox Effect is the test blog for techForum. This is where I, pchelptech, try out new stuff - jQuery functions, CSS3, strange and dangerous formatting, just to see what it looks like, before clicking PUBLISH POST in the techForum blog. In shot, The Sandbox Effect is for when the preview button just isn't doing it for me.

Today, I'm trying drop shadow formatting to see if it works.

Here it is. Impressive, eh?
