Intent on creating content and solving life's mysterys I typed the above question into several major browsers and noted the results.
With Google when hitting 'I feel lucky' I got some mod site (Reaction) , updated in January this year. So not dead, just...old: http://www.rq3.com/
Ask Jeeves, fared a little worse and gave me a French site as my first hit. Because this site was French I immediately spammed it's webmaster, trolled the email addresses, signed them up for kiddy porn and DDOS'd the host with my best script. When that failed I followed the second link: http://www.chinadaily.com.cn/en/doc/2003-10/17/content_273218.htm. This was more sobering. An earthquake had left 3 people dead and some 500,000 homeless. My concerns are small.
Then I tried Yahoo because I wanted the US Government to know my name and underwear size as sold to them by Yahoo, sorry Blizzard, sorry AOL inc.
They gave me the Irish Quake community website. It was actually interesting and contained relevant news fom this month. Notably that id want betatesters for the new Quake Wars. Here: http://www.quake.ie/
Which search constantly comes up no matter what I set my default search to? Which one does IE constantly recommend regardless of my actions? So finally I tried MSN. It repeated Google and gave me Reaction Quake 3. Being a dilligent journalist I followed the second link to get more links for you. This one meniotned an earthquake in Indonesia that had killed 3,000: http://news.bbc.co.uk/1/hi/world/asia-pacific/5022558.stm
So did my intrepid internet exploring result in an answer? Is Quake 3 dead? Well, sort of. But there are also a lot of earthquakes out there. Remember earthquakes could be anywhere, they could be your best friend. Report all Earthquakes to your local police force.
