I'm having a serious case of the brain farts.
In THEORY I know that I should be able to use a function filter to have Twitter Tools use ugly permalinks in tweets (to force shorter urls and yet keep 'branding').
Since I KNOW I'm way short on sleep, does this look right in theory?
// Add hook for Twitter Tools URL shortening filter
add_filter('tweet_blog_post_url','makeShortURL');
// Function to make the short URL
function makeShortURL($url) {
global $post;
$shortpost = $post->ID;
$shortpost = "http://domain.com/" . $shortpost;
return $shortpost;
}
