Well, since the problem has been resolved some time in the last couple of days, I'll just clarify:
Normally, movielens seems to only need about 10 ratings to place a movie in its similarity model. When I had posted the message, there were a couple of films that had moved well beyond that point (Crank), but similarities had not been calculated.
Likewise, there didn't seem to be many changes to my top picks, which are often very volatile. My speculation was that the routine that calculates the movie similarities had not run for a little while.
baa-- Good eye. The process was indeed offline. I found a bizarre garbage collection bug that only occurred with Java 1.5. I won't bore you with it.
The other item I was curious about has also returned: "There are n movies matching your search:" and it sounds like some search glitches have also been fixed.
This one was requested by a user, who emailed us and said, "Hey, can you bring that back?" and I did last night.
However, I am always fearful that fixing bugs will bring another 70 of them crashing onto my plate! ("No good deed goes unpunished") [:(] We have 205 issues currently filed, and it would be bad to get trapped into addressing them all!
