I worked at Facebook last year and Google this year. I don't have an insider view of the other companies but some of my closest friends work at all of them except Netflix.
My guess is that none of these will stop growing in the next few years, but Facebook is especially undervalued. They execute on new products faster and better than the others listed, so regardless of current sentiment they are probably not going to fail any time soon.
I chose Netflix because I have the least evidence to suggest they will remain stable, but would say the odds are <10% any of these have a lower market cap in 5 years than they do now.
