The hReview microformat is perfect for marking up offsite comments (posts with pingbacks). What is a comment if not a review? Better yet the format already features a summary class that can be used to quick and simply summarise the points for readers of the original post.
By Default WordPress will take a set number of characters from the source of a ping and present these as a comment. This is pretty useless for the most part. This plugin will parse the source of a ping looking for an hReview to see if better information can be gained about the opinion of the author.
If that information is available the content of the comment will be replaced with the summary presented in the hReview.
The following is an example of the HTML that you can use to do this if you are writing about another site.
<div class="hreview"> <p class="item">Bob over at Bob's Blog has written about <a class="fn url" href="[link to the article being commented on]">the subject of the review</a>.</p> <p class="summary">this is where you summarise the content, this will appear in the comments of the target blog</p> <div class="description"> <p>This is where you say what you think in full, using full html</p> </div> </div>
