What happened to google search?

Google search is acting really weired recently. First off, my homepage disappeared from the search results by using keywords "Pan Yu homepage" (without the quote marks), which used to be the second results on the first page, but now totally disappeared (I haven't found within the first 10+ pages). Instead, lots of other web pages which neither contain consecutive "Pan Yu" nor are homepages of any sort are listed. At the beginning, I was wondering whether this is caused by the "personalized search" just launched, though I don't remember enabling it. I logged out my google account, searched again, nothing changed. Then I asked my labmate Edward to try the same thing for his homepage. This time, more counter-intuitive thing happened. When he typed "edward sim", his homepage appeared at the end of the first result page, however, trying "edward sim homepage" returned irrelevant stuff as what happened to me.

I know google has integrated news results to the normal search results a moment ago, but apparently what listed for our homepage search are not news. Google is acquiring a lot of companies and participating lots of other services outside the search world. While it used to move cautiously, it is more aggressive nowadays. I'm a little worried about google because it used to be based on pure technologies and people are really admire the objectiveness and spirit behind this. Growing into an empire that dominate the web may not be bad, since a lot of innovations and good services really benefit everybody and change the world. But except all those services and the so called google operating system, I really hope the heart of google can always be the same, being dependable and reliable, moving solid moves.
