I think you're doing a good job (and gave you a thumbs up on one of your reviews). My guess is the problem is that you're reviewing courses that aren't very popular. All of my highest thumbs up'd reviews are from places like Highbridge or Idlewild. Tons of my reviews are from courses in Germany where no one really reads (let alone like) them but I put a lot of time into updating the course page with pictures and stuff. Also note that the majority of people who use this site aren't members and can't thumb. Just keep at it!
