Back to the future

I've restored the ability to toggle between displaying 200 words of blog content or just headlines.

When looking at a blog category you will now see a link that says "Show just headlines." Clicking on that link will display the same articles, with just the headlines and names of the blogs. The "More..." button will continue with just headlines.
