Not intending to sound ofensive nor harsh but 99% of people don't really care with what is happening.

And... as an experienced sysadmin (+15 years), I really disagree that get a VPS+Nginx+Apache+WP+MySQL+OAuth+Akismet running, and them, maintening it long term is as trivial as some Github/Tumblr pages (or a static site generator) with a pasted JS in the bottom of the theme file.

edit: added WP to the list of things to setup.
