The one thing that I've learned from Orkut so far: some people aren't too picky about their friends.

For those interested in these things (and you know who you are), the Orkut site apparently uses Linux servers and a Solaris server, but the pages are based on Microsoft ASP code running on top of Sun Java System Active Server Pages, aka the former ChiliSoft ASP-on-Unix solution. (For those of you inside the Orkut bubble, note the .aspx page names).
