Of course, and used Parked since mid 2007. I moved just my Sedo zero clickers to Parked. The benefit: keyword/description meta tags get you more visibility in Google. Customized content. A multitude of templates with customized images. Multiple clicks count as such.
I just want to see more stability from Yahoo feeds before moving over more domains. Sedo revenue has doubled since December and PPC has dropped a bit at Parked.
