Ultraminimalist blogging armature (less than a platform, or even a framework)
My recommendation for now? Don't.
Put it somewhere your webserver can see it. Do the things you need to do to get a rack app working under your server. Because this depends on ruby 1.9, be careful if you're using Apache/Passenger.
Run bundle install
You'll need to create a database.yml file. It should look like this:
---
:adapter: mysql
:host: db.example.com
:database: my_blog
:user: user
:password: drowssap
Change the values as appropriate.
Pre-create the database. Don't worry about pre-creating any tables. The app will do that on startup if needed.
Tweak the css as you see fit.
