Twitter URL Shortener

I generated a URL under this new blog that is shorter than the URL generated by Twitter under the shortener.  The link that was listed on the tweet was the link, but the url link was a link which was longer than the link generated by my blog (which then forwards to the page).

This is the link for this page:
This is the link Twitter creates:

Update 2:
Every post/update generates an error w/ the plugin I post blog entries to Twitter w/ cause my URLs are shorter than Twitter’s shortlinks. (=
