Do you think that the similar users approach of Lucene is similar to the
"most similar users" of mahout?

Hi,

Here is an example of Lucene MLT-based "similar users" functionality:
http://www.simpy.com/user/otis
(it's based on tags)
Of course, MLT can be tweaked with a couple of parameters, so it can be
adjusted depending on the need.

I like Taste's mostSimilarUsers(), but I wish it exposed/returned the
similarity metric, so one can use this method and see exactly how similar
those most similar users are.  For example, an application may want to show
or hide similar users based on this similarity "distance" from the given
user.
