今天不知从哪里点到这篇文章：Jeremy Zawodny's blog: PageRank is Dead
仔细阅读了一下，很有道理……
粗粗翻译了一下，水平有限……

PageRank已死
我想花点时间来哀悼正在成为过去的 PageRank，这个使Google成为我们所热爱的搜索引擎的关键秘密。
一些人也许在讨论正是Blogs杀死了PageRank。但事实是，整个网上世界每隔几年就会发生深刻的变化。并且，不管你是否相信，PageRank已经老了。在Internet的时代，PageRank可能已经踏入中年。
它并没有没有被宣布死亡，但是时间已经接近了。征兆已经有很长一段时间了。
你看到，PageRank在这一刻还是个简单的有才气的概念：用网络自身的结构来决定哪个是流行的哪个不是流行的。不过那时在我们之后。Google将不再能够独立地决定这种流行。就像许多公司一样，他们也非常关心卖什么和广告商想要什么。许多推测认为Google也许正在对不让Blogs污染他们的搜索结果的各种压力作出回应。
近来有许多关于Google正在把他们的Blog从索引页移除（或不移除）的讨论，然而，人们攻击错了目标。Google没有必要移除他们。只需要很简单地用一个可靠的方法将它们区别开就行。这样的话，这些Blogs可能被处罚（给予一个低PageRank值）。并且，无论你是否相信，如果你有一个很好的网站地图和一些用于初始化的Blogs，那并不是十分困难的。
这已经发生了。并且结果比想象的还差。现在[有时]在Google里搜索"jeremy"和以前的结果有了很大的区别。注意，Google现在相信我的主页比我的Blog重要得多。因为缺乏更贴切的术语，我称之为被减速。
（看起来Google只有一部分改成这样了，如果你有足够的耐心，你能从他们的搜索群得到以前的答案。那就是我怎么得到那2张屏幕截图的原因。到目前为止似乎是50/50的机会，至少西海岸是这样的。）
我不是第一个搜索结果并不是重点，我从未希望过那样。
让我们诚实点。我的主页非常糟糕。没有其他任何人连接到它。肯定，有很多旧的连接，但是让我们看看Google告诉我们什么。有600左右的页面连到我的主页，然而，有超过1800个页面连到我的Blog。有三倍的页面连接到我的Blog，而且我保证他们是更有意义的。他们是更新的。他们常常不仅仅是指示器，因为那儿有关于我的注释或者我所写的文章。
无论如何，得出您自己的结论。
Google有一个真正艰难的问题需要解决。就像Heisenberg 不确定原理。当人们开始懂得PageRank是如何运作时，PageRank开始停止运作了。Google尝试“理解”网络的行为造成了网络自身的变化。Blogs只是现阶段唯一的一个例子。奇怪的是，不像以前Google所碰到的许多问题（例如：搜索引擎优化公司；连接广告商；Google炸弹），Blogs并不是设计用于智胜Google的。它们只是碰巧使用了网络和我们长久以来一直应该使用的超连接。现在似乎他们将因为这个被处罚。
有趣的是，不知道Inktomi和Microsoft怎么解决这个“问题”。
哦，我应该注意到，这些应该都是bug并且我只是正在将它作为借口漫游。
但是你们都知道那个，是吗？我的读者是聪明的，所有他们三个。:-)

PageRank is Dead
I'd like to talk a moment to mourn the passing of PageRank, the secret sauce that made Google the spicy search engine we once knew and loved.
Some might argue that blogs killed PageRank. But the fact is, the online world goes through pretty impressive changes every few years. And, believe it or not, PageRank is old. In Internet time, PageRank may have been well into middle age.
Its death hasn't been announced yet, but the time is near. The signs have been around for quite a while.
You see, PageRank was a brilliant yet simple idea at the time: use the structure of the web itself to determine what is and is not popular. But that's behind us. Google is no longer concerned solely with what's popular. Like most companies, they also care a lot about what sells or what advertisers want. Many speculate that Google is responding to various pressures to keep blogs from tainting their results. Perhaps.
With all the recent discussion of Google removing (or not removing) blogs from their index, people have been barking up the wrong tree. Google doesn't have to remove them. The simply need to identify them in a reliable way. Then they can be penalized (given a lower PageRank). And, believe it or not, that's not terribly difficult to do if you have a good web map and a few blogs to use as starting points.
It has already happened. And the results are less than ideal. A Google search for "jeremy" now [sometimes] yields something far different than what it used to. Notice that Google now believes that my home page is more important than my blog. That is, for lack of a better term, retarded.
(It seems that Google has only partially deployed this. If you play around long enough, you can get the old answer from one of their search clusters. That's how I got both of those screenshots. So far it seems to be a 50/50 chance, at least from the West Coast.)
The fact that I'm no longer the first result isn't the issue. I never expected that to last.
Let's be honest. My home page sucks. Nobody links to it anymore. Sure, there are a lot of old links, but let's look at what Google can tell us. There are roughly 600 links to my home page while there are over 1,800 links to my blog. There are three times as many links to my blog, and I'd argue they're more significant. They're newer. They're often more than mere pointers because there's commentary about me or what I write.
Anyway, draw your own conclusions.
Google has a really hard problem to solve. It's not unlike the Heisenberg Uncertainty Principle. PageRank stopped working really well when people began to understand how PageRank worked. The act of Google trying to "understand" the web caused the web itself to change. Blogs are only a recent example of that. Oddly, unlike many of the previous problems with Google (see also: search engine optimization companies; link spammers; google bombing), blogs were not designed to outsmart Google. They just happen to use the web and hyperlinks the way we should have been using them all along. Now they're being penalized for that, it seems.
It'll be interesting to see how Inktomi and Microsoft handle this "problem" too.
Oh, I should note that this could all be a bug and I'm just using it as an excuse to ramble. But you all knew that, right? My readers are smart. All three of them. :-)
