I have this site http://www.bloginspace.com and I am trying to determine the value because I am thinking of selling it. The concept is totally viral and we keep adding backlinks and double opt-in emails everyday. It is a PR 6 site, 2420 google links. http://www.urltrends.com/viewtrend.php?url=http://www.bloginspace.com What do you guys think? What is the value of a site/campaign like this.
