Topic: Bootstrap theme
I just set up a new theme for Nibbleblog using Twitter Bootstrap. Using that, you'll have a responsive blog!
The theme uses the Bootstrap default theme and, for that, it is really gray and 'saltless' but, customizing it to make it nicer, is just a matter of changing the css file included.
You can see a demo at my blog: http://bootswatcher.com/blog (it's a more customized version to work with the rest of the site).
And yeah, the page is about a software to customize Twitter Bootrap styles (guess what: you can use it to customize the look and feel of your blog!)
The theme is on github: github.com/DezminSites/nibbleblog-bootstrap
I hope you like it!
