I dunno, easter egg or not, adding special behavior to the browser for any url which contains /jwz/ seems really hackish and unprofessional. Those were very different times, I guess.
No, today still there are huge multinational companies that allow their programmers to have fun doing similar things. Besides there being nothing "unprofessional" (sic) about it, it also can bring in tons of good publicity and viral interest.
Do you have any examples of hue multinational companies that allow programmers to insert Easter eggs? I can't think of a single business software vendor that has Easter eggs anymore. Even MS has stopped doing it.
I do all my work in big companies and they have all been universally against humorous test data, humorous naming conventions, or an sort of Easter egg.
