Yahoo! has a new Shortcuts plugin for WordPress. [here]
When installed the plugin adds a button to your Write Post screen. When you’re done writing your post you click the Review this post button and the plugin looks through links etc in your post so that it can add stuff to it.
Once the plugin has reviewed your post you can add or remove what it thinks you need in there.
It’ll also add flickr pictures related by keyword to the content of your post too.
It’s worth a download and install.
