I'm surprised there aren't more things like this out there. With GitHub, Tumblr, etc. basically allowing you to host almost whatever you want it's surprising people still pay for hosting their small, personal-ish websites.
For 1, you can use tumblr as your media CDN, i.e. post photos, videos and other bandwidth heavy stuff, and use the tumblr API to access and display them on your website / blog.
tumblr actually allows you to use custom domain, i currently have 4-5 domains where my clients only update once a year for an event. i make up a custom theme and them take it over. no fuss around with hosting it.
Yeah, especially because you can host it on a custom domain, and having your website in a git repo is pretty nice, using githuh for your blog / homepage / whatever seems like a no-brainer.
