I have a wordpress blog i.e. bruno.wordpress.com I would like to use github:gist.
I paste my code in gist and get a link like: https://gist.github.com/1323748
Is there a way to show this code in my blog? (rather than just a link to the code.)

As scribu mentions, you can do this on a self-hosted WordPress site with a plugin. In WordPress.com, though, you don't have access to these plugins and must depend on the oEmbed support WordPress.com extends you by default.
Your best bet is to contact their support team directly and ask if/when they'll have support for Gist via oEmbed.
It may not have been possible in Oct 2011, but it is now. hosted wordpress.com automatically recognizes gist URLs and will embed them.
