Yahoo! has recently released a WordPress plugin called Yahoo! Shortcuts into beta.
This plugin takes all that is beautiful from Yahoo! and places it within reach of your blog. Basically what it does is it allows you to enhance blog posts with pictures from Flickr, and the search and maps and other parts of Yahoo! itself. Then you can use that content to enhance your posts. Personally, I’m not fond of the whole Intellitext type links, but the embedding of images and useful information as badges is definitely a “fall in love at first sight” type of blogging tool.
I definitely recommend playing with this. Let me put it this way. It doesn’t hurt anything and makes your posts a lot more user friendly. So why not?
