Obviously the C# guys are on their yachts or flying their planes at the weekend. The Ruby people would have web access from their security guard jobs.

The same trend seems to hold for other "corporate" languages, such as PHP, .Net, and C++:

Interesting, but you've got to factor in the fact that C# is a much more specific search term than Ruby...

C# searches are probably mostly about C#. The Ruby result would also contain all the searches involving "Ruby" that aren't related to the language at all.

The C# 9-5 theory also supported by the long term view, showing yearly drops between mid-December till January.

You mean "since 2004".

Yup.... C# vs Emerald yields the exact same graph. Is Emerald a new language we haven't heard about it?

As someone who codes in C# during the week, I would much rather play around with other languages on the weekend to gain new insight and motivation. If Ruby was a popular 9-5 language, I would expect to see a similar drop over the weekend.

I hadn't noticed that Google has started to tokenize properly things like C, C++, C#.

Probably because I don't use them recently.

Heh, my case exactly. ;-)
