CodeClimber has a neat post on how searches on C# compare to searches on Ruby.  C# is clearly getting more searches (even before you factor in all the various ways people search for C#), but the difference is much more pronounced during the week.  Maybe all us C# devs are getting burned out by the end of the week and aren’t doing much hobby developing on the weekends?  Or maybe the ones doing hobby development aren’t having to run to Google as often for answers as the peeps doing 9×5 development (no disrespect intended, there’s nothing wrong with Googling for answers instead of memorizing obscure API calls).
