    Wordpress would like to have a word with you.

They host 72 million blogs [1], and I'm sure that the total number of WordPress blogs wouldn't be so high if they all had to be self-hosted.

Yes, but I think it would be difficult to argue that Wordpress' popularity wasn't due to its being easier to install than Movable Type, at first. The ecosystem of plugins, themes and shops whose entire purpose is hacking Wordpress suggests that its still primarily used as an installed application, though I wouldn't doubt they get seriously good business from their hosted service.

81% of the internet do not use Wordpress: http://venturebeat.com/2013/07/27/19-percent-of-the-web-runs...

~20% of the web is still not chump change.
