Well, I was going to answer this question, but Dolores Monet did it for me. I switched to Hubpages from two other article submission sites because Hubpages offers THE BEST formatting options for presenting information online. And like Delores says, it's easy to do.
My advice is to make use of them in your hubs (along with a lot of white space and sub-headings for easy reading). I usually add at least 1 photo, 1 video, 1 link, and one other capsule to my hubs, as well as in-text links when appropriate.
