Google Turns 5
Gantic writes "The BBC has an article on Google's 5th birthday. The popular search engine now handles over 200 million queries a day and the word "Google" is now a noun, adjective and verb. Lets see how long the most popular search engine in the world can last, here's to another 5 years and more Google!"
What OTHER search engine do you still use, and why?
When Teoma etc came in I thought Google would be in for some tough competition - but everything has blown away in front of them - a case in study for technology and services analysts for years to come.

Their PageRank technology is something that they have leveraged on . .
[PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important."
Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for your query]
Their continuing language translation initiative and innovative Google Labs keep up the momentum in their favour - searching now is heading for Google thats it, nothing else comes to mind !
Also there have been amazingly few outages too on their side; as they add more and more pages to their cache and more services !
I've often wondered why, in all of the attempts to mimic google's toolbar, no one has ever reproduced the handy pagerank indicator; I began hacking at it, wondering if I'll be the first, only to run into a brick wall.
/search?client=navclient-auto&googleip=O;216.239.5 3.104;131&ch=53856195705&freshness_check=3f1eAVUrj Mj2meFfx-IZI&ie=UTF-8&oe=UTF-8&features=Rank&q=inf o:http%3A%2F%2Fslashdot%2Eorg%2F HTTP/1.1
Here's the request it sends; if you duplicate it with telnet or whatever, it really will spit out slashdot's pagerank:
GET
User-Agent: Mozilla/4.0 (compatible; GoogleToolbar 1.1.70-big; Windows XP 5.1)
Host: 216.239.53.104
Pragma: no-cache
Connection: keep-alive
But there's a little program, the ch= field. That's a special hash of "http://slashdot.org," and if you don't send it, it doesn't work.
So as I continue attempting to work out the algorithm for this mysterious hash, I wonder: why has Google gone to such great lengths to make sure nobody duplicates the toolbar's pagerank indicator? Would a copy of that feature for Mozilla's google toolbar really be so awful?
I made a PHP/MySQL library that prevents SQL injection & makes coding easier!
