If you’re using version 3.5 of the Blog CFC you can get Apache to create some nice URL to access posts which you’ve created aliases for. Create a .htaccess file in you root directory and pop in it the following:

RewriteEngine on
RewriteCond %{REQUEST_URI} ^/go/([0-9]*)
RewriteRule ^(.*) /index.cfm?mode=alias&alias=%1 [L]

You can try it if you like.
