Include a Twitter @username in your blog post and Twitter Tag will automatically create a link to that users Twitter page and will send a tweet telling them that they’ve been tagged in one of your posts. Twitter Tag uses Tiny URL to include a URL to the blog post in the tweet.

The output is customizable on nearly every aspect. With or without profile pictures, tweet date, usernames before tweets, hashtags and usernames as links etc. etc.

There is also a widget to easily add a Twitter feed to your header, sidebar or footer, if your theme supports it.
