I can also add Yahoo! Finance, not exactly a personal home page ;-)

Then there are so many others high-traffic and successful web sites/portals/applications written in Perl, that I think it's not wrong to state that Perl is the most adopted, widespread and popular language for such (big) web applications. Maybe PHP can challenge it (only for popularity I mean,) not Java, for sure.
