I am not so sure technology stack is entirely unrelated to failure rate. The stack you pick may influence iteration speed, hosting options, developer availability, uptime, reliability, security and costs.

Twitter would have failed had their scalability problems persisted.

In fact, I remember "Six Degrees". It was more or less Facebook, but in the late 90's. IIRC, they ran Cold Fusion on Windows.

Some say that Friendster failed mainly due to scaling issues. http://highscalability.com/blog/2007/11/13/friendster-lost-l...

You have a valid point there :)
