With Blogo you can add Codeblocks to your posts really easily! It's a fantastic feature for programmers that want to share their code on their blogs.
To add a Codeblock all you need to do is click on "Format" in the Menu Bar, and select "Code". Alternatively can use the keyboard shortcut "CMD + SHIFT + K".
Blogo also does a pretty good job at syntax highlighting, with support for over 30 different programming languages!
