How to tell when your on a shed load of CSS Galleries

My Google Analytics for the past 20 days are an interesting read. Over 80% of the hits base6 has received are from referral sites, almost all of which are CSS galleries.
I have mixed feelings about these results. The data proves that you can’t guarantee solid client leads using gallery and design sites as marketing tools.
They are great to get you noticed by your peers and excellent for feedback but chances are the people who visit these sites are like-minded individuals who don’t want to purchase design services.
