1) abbeyvet - Given the nature of your clients (Small business) how would they have come across the important of selling on eBay and hence requesting that as a feature. Also is this just a once off or is the ability to sell on eBay something thats becoming more popular?
I think you missed abbeyvet's point completely: EVERY website is a one-off! Every business has unique needs!
I think there is more opportunity in identifying niches and providing a tool that can serve those niches well, minimizing the customization needed to fit the customer's needs to the tool's capabilities
No, "selling on eBay" is NOT an appropriate feature for a "web builder". OK, perhaps one that is bloated and tries to be everything to everyone. But then there's no way it's going to qualify as "simple".
