Lightspeed will prolly kill me for this.. but oh well.
I've found that Tawneestone.com doesn't convert as well FOR ME, as say, ls-sorority.com or university. My lifetime average from lightspeed (100% TGP traffic) is 1:130, and tawneestone.com doesn't come close to that. I think it may be that the surfer sees "hrm, only one girl.. naw, don't think so", since I "market" stuff rather honestly like that.
I've found though, that pushing another LS site with tawnee content gets VERY nice conversions. Who knows what the kicker is, it could even be my gallery design. In other words, push what works for YOU, not someone else. Who cares if someone else can convert 1:1 with whatever site, if you can't that is all that matters.
Sorry Lightspeed/Tanker, you're two damn good guys to work with.
