The most recent update I can find from them (May 2012) said that they still have 4-day workweeks half the year, May-October: http://37signals.com/svn/posts/3186-workplace-experiments-a-...

Have they gotten rid of it entirely since then?

Ah, yes, you are right that they still have it around. The first time they did it, they were hoping that it would work year-round and they had to get rid of that idea. I'm glad they are able to make it work periodically, though.
