What Programming Languages are Used Late at Night

Stack Overflow has a good post on which languages (or rather Stack Overflow tags) are used mostly during business hours, and which are used at night.

tsql, SharePoint, Java, etc. are used during the day, and Haskell is the clear favorite among night owls.

Haskell often catches flak for “being a hard language to hire programmers for.” This data suggests that, while there clearly aren’t as many Haskell programmers, many of them use it recreationally out of interest, not because it has the potential for a high salary. Such people would likely jump at an opportunity to do similar things during the day.

Would you hire such a person?
