Telephone Content Management System by DHS
Technophobes who need websites for their businesses would much rather phone somebody up to change the content or design of their website than learn how to use a CMS (or even send an email). This is an idea for a call-centre business to change that with an army of friendly, tech-savvy support people.
Business model could be inspired by the insurance industry with a monthly/annual fee and different pricing bands depending on how demanding the client is.
Webdesign agencies could refer their customers to this service for ongoing support and earn a commission. It might also be possible to buy bundles of existing support contracts from agencies.
It could be Wordpress-only initially and expand to other CMSs in due course.
