Turn your blog into a pastebin with syntax highlighting provided by other plugins.
Q: I don't like the /paste/ base, what can I do.
A: Define WORDPRESS_PASTEBIN_POST_TYPE_SLUG in your wp-config.php. Please notice that you will have to take care of redirecting old pastes to the new slug yourself. You can use a .htaccess or any other method you like to do that.
Q: I get an error that the post type already exists.
A: Define WORDPRESS_PASTEBIN_POST_TYPE_NAME in your wp-config.php
