I have initial thoughts how this might be useful some folks:
1. Webmasters - plug these user editable sections into existing webpages and let your users update content themselves, without involving you.
2. Website owners – if you don't know HTML or FTP, you can get your webmaster/designer to do a one time setup and henceforth, you can update the content without involving them, saving time and money.
3. Designers – since the basic user-updatable blocks are essentially DIVs, you wouldn't be constrained by a CMS or blogging engine's template layouts – your imagination is the limit.
Really looking forward to hearing what you brilliant folks think!
