It looks like there’s a new WordPress install business that’s geared towards helping people set up business blogs using WordPress.
It claims you can set up WordPress for free using its service, so its business model seems to be based on affiliate sales and advertising. However, on signup the site does ask for a PayPal email with no obvious explanation why.
Of course, if you want to set up a personal (i.e. non-business) blog using WordPress, you can always take advantage of the official Install4Free site.
