Other Popular Websites

Those with perl are probably going back to the first dot com era (aka Web 1.0, ~1998). At that time, perl was basically the only game in town (secondarily: Java). (i don't recall what amazon and ebay were in… was it perl or php? how about imdb.com?)

most php follows starting in early 2000s, that's when PHP quietly surpassed perl in all battle fronts.

it'd be interesting to know what some of the chinese sites uses, and porn sites, as video porn sites has traffic that's probably a magnitude more than others.

as for Microsoft sites… i suppose they are ASP for older sites and C# with “.NET” for new?
