Time-based preferences for recommendation

[Anatoliy Kats]

Hi,

There was a conversation some time ago about incorporating time 
dependency for preferences: 
http://thread.gmane.org/gmane.comp.apache.mahout.user/2951

Has there been any more discussion about this?  Has anything been 
checked into Mahout?  Is anyone working on it?  I might be able to pitch in.

Thanks,

Anatoliy
