Well, say you have 250 domains that you want to develop, but you don't have a year to do it. If there was something like whypark that gives you instant "developed" sites with content, they would get indexed like crazy without all the work of conventional development. AND, you could promote the sites all you want without being penalized for having backlinks. AND you could keep 100% of the revenue as well. Maybe down the road someone will do it.
Good idea for someone to build a business, while at the same time making us .mobi'ers very happy.
If I knew the first thing about creating a service like this, I would do it. Someone could get rich doing this with just a small percentage of the 600K .mobi's registered.
