I've been signed up to The Sample for a few months now, getting one newsletter a day.

Each newsletter includes a link to rate it from 1 star to 5 stars.

I consistently rate the newsletters I receive at 1 star! About 5 good newsletters have been delivered over this time, these have been rated from 2 to 5 stars but I haven't received more of that type.

The recommendation system seems fairly ineffective, I just receive junk each day.

Or would this be reflective of the state of newsletters (98% junk, 2% good)?
