Same here. I never really used third party domain software. I used Google Fonts for a while, but I find it pathetic to have some font files and some CSS loaded from a different server than mine. Google Fonts (and every CDN) can be a lot slower than my own server. Sometimes, the site hangs while "waiting for google.com". Silly.

Also, Google Fonts might be Google Analytics in disguise. Who knows.

I use Piwik for tracking, but the self-hosted version. I don't even use newsletter services. I bought a cheap newsletter plugin for Wordpress which I use as an autoresponder email course.

But delivery is all that matters they say. And yet, all Mailchimp and Aweber and whatnot goes 100% to my spam folder automatically. I believe the delivery argument is a myth.

The best part: Decision making is much easier. "So, your product can't be installed on my own server? Bad luck, I won't become your customer."
