Actually Joseph used one of the soundest research methods I know of. He
published an obviously flawed "Strawman", didn't pretend it was anything it
wasn't, and the wisdom of the group began fixing errors and filling in
blanks. So, just like "Nail Soup", a basic seed is evolving into a matrix
that has more information than any single one of us could contribute.

Thanks for taking the initiative,

Peter.

Friends,

As Tim Bray suggested I've made my best to drop the guesses on the list, and
show only information I know is either true or reported by some credible
source.  When no information is there, I just left a question mark.

I have also updated the list with the information Chad Perrin, Charles
Nutter and Tim Bray added to it.  This is the list so far, again open for
improvement:

1 Yahoo FreeBSD
   PERL, PHP, Proprietary
"Also Python and Common Lisp" Chad Perrin


2 MSN   Windows Server 2000/2003, Some FreeBSD
   ASP, ASP.NET
"I believe they're still using some FreeBSD systems at Hotmail, and all of
Windows is behind free unix firewalls through a proxy service." Chad Perrin

3 Google.  Linux based or unknown servers
   Python, C, Proprietary, Java

4 Baidu.com  Linux based unknown.
  ?

5. Qq.com  Linux based unknown and Windows 2003.
   ?

6. MySpace  Windows 2003 / 2000 some Linux unknowns too.
   Coldfusion
"Migrating to BlueDragon.NET, which uses .NET as the back end for
ColdFusion... currently... on a ColdFusion 5 back-end" Chad Perrin

7. sina.com.cn  FreeBSD, Solaris 8, Linux based unknowns,
    ?

8. Yahoo Japan Like Yahoo at 1.

9. 163.com China  FreeBSD and some Linux based unknowns,
    ?

10 Live.com     Windows 2003, Linux unknown servers
   ASP.NET

11 eBay.com Windows 2000/2003
PERL, Proprietary, Java J2EEE

"eBay is running a crapload of Java... they used to be a solid ASP site
(pre-.NET) but switched to Java because the ASP stuff scaled horribly...the
site has Sun/Java branding...it's probably safe to assume Java's involved. "
Charles Nutter

12. Sohu.com China      Linux unknown servers
      ?

13. YouTube.com Linux unknown servers
      ?

14.     Yahoo China     Like 1

15. Microsoft   Windows 2003 / 2000, some FreeBSD at Hotmail, and UNIX
based firewalls.
      ASP.net, ASP

16.   Wikipedia Apache, very little FreeBSD
        Mostly PHP, some minor PERL, Python and some Java for the English
search.

"a grand total of one FreeBSD server... The servers are primarily running on
Fedora Core 3-5...The MediaWiki software is all PHP.  MySQL ...it's classic
LAMP platform." Chad Perrin

"but Wikimedia do use Lucene  [Apache Java based text search engine]
for at least the english search"   A. S. Bradbury

17. Amazon.com  FreeBSD, Linux unknown servers, Solaris 8, Netware
     PERL, Proprietary, more?

18. Orkut.com   Linux unknown server
    "ASP.NET"  Tim Bray
