Hello,
What we want to prove is that in this industry, paid customer acquisition costs are so high, that it's better to save these by increasing your server costs. We offer free web hosting, which essentially gets promoted alone. We have higher server costs, true, but it's still worth it. We earn money through Google AdSense on our site and through paid upgrades we'll soon be offering.
We could very well provide VPSes, cloud services, domains and/or SSD web hosting where you could also host unlimited domains (now you can host one domain per account)
