Yahoo today released a wordpress plugin for bloggers to show relevant content (read Yahoo content) in blog posts. This wordpress plugin finds Flickr photos, ticker symbols, products, yahoo maps etc which can be included in blog posts as links to relevant words or as badges. If you put lot of flickr images or a financial blog looking for company info then this plugin is useful to you otherwise its useless.
After installing the plugin you will see a module “Y powered shortcuts” in your write panel. It will find relevant links when you write the post based on the text, you can click “Review this post” button to include these in your post. Either link keywords with links or as direct or in a mini search box as hover links. Flickr photos, yahoo maps, products from yahoo shopping can be included in the content.
If you want to give free advertising to Yahoo go and get the beta plugin.
