I just saw a demo of how the Yahoo Shortcuts Plugin could super enhance WP blog posts.I may not use it myself because I personally hate tooltips,which was a big feature.However I do like the option to convert a link to a badge that would insert a map into the text,making it look like a page a newspaper or magazine which is a look I p[ersonally really go for.Then at the bottom of the write post editing field is the flickr option.You select the pictures set you want to show and voila all your flickr photos relating to that post are in nice neat thumbs at the bottom of your post.
Pretty sweet.
