Can't they keep this damn system up for more than [10,20,30,40,50,60]
  minutes at a time?  HEY GOOGLE!  You guys know anything about computers?
This is just a
 [technological,sociological,google,embarassing,tragic,inexcusable] failure.
What's with this [stupid,insulting,elitist] invitation-only crap?  What about
 allowing [the common people,shut-ins,technophobes,luddites,unpopular people] 
 too?  Does everyone here have to be [Linus Torvalds,Cliff Stoll,
 the captain of the 
 football team,a Supreme Court justice,a Democrat front-runner,Janet Jackson]?
 This is worse than high school.
This is all just [Friendster,Match.com,Slashdot,Usenet] done badly.
Don't these idiots know anything about [sociology,social
 networks,networking,people,human behavior]?  Haven't we learned anything?
Have you seen the terms of service?  They [say you must be 18,can terminate
 your account at any time,own your postings,forbid spiders/robots,use
 cookies,are longer than the MS EULA]!  Orkut = NAZI GERMANY.
What's with the "[Trusty,Sexy,Cool,Fan]" markers?  Looks like
 [sexist,elitist,communist,Stanford] bullshit.
Don't they know that [Friendster,Amazon,Match.com,Usenet,LJ,Slashdot] tried
 that feature [2,3,4,5] years ago and it was an abysmal failure.  Have we
 learned nothing about social networking?
I can't believe [I,my friends,my friends' friends,my worst enemy,a Star Wars
 fan,an S&M freak] can send a [message,crush note,complaint] to [me,my
 friends,my friends' friends,everyone in Antisocial,the whole Star Trek
 community,Emacs users,the Friends fan community].  Orkut people know nothing
 about security! 
[Friendster,Match.com,Usenet,DecNET] did this [2,3,4,5,6,7] years ago.
