With the blog posts blizzard makes, they don't do a new entry but instead add in an edit when they post something new. However the blue tracker can't parse the edits.

For example look at the following page with the blue tracker, and the source. From the blue tracker it "bumps" the entire blog post, including the new additions. Thats fine and all, but the actual blog post lists the recent additions in a different color (red to be exact). So it makes it hard to read the blue tracker version quickly to see the new additions.

Now it would be nice if the blue tracker would gain the ability to parse these "red" changes and have them be red, or some other color then the old stuff.
