Re: judging news readership based on article access times

These programs (and outgoing feeds) tend to access the whole news database
so if you are using some kind of score based system, it wouldn't effect the
outcome.  You could reset the mod time for accesses that don't count.

It's not a very pure form of information but looking at it often and 
long enough would probably provide correct conclusions about interest 
in a group.
