What's up with accessories on the wiki?

You can place videos, spoilers, lists, html, ascii, and there's H2, H3, H4. There is also a XL picture size and center picture option. It's basically the forums but on the wiki.
What the hell? Is it meant to be like that? 
look at the PlayStation Move page for example:  http://www.giantbomb.com/playstation-move/59-36/

I didn't really ever notice you could put videos in the wiki pages. The PlayStation Move page does look really weird though because of it.

Well I am not liking this at all. I wonder why you can do it on those pages but not any others. I bet it is just a mistake.

It's probably because those pages are separate from everything else. They don't show up in the search results, for example, which was a huge problem for a specific quest. Try putting "Playstation move" in the search field, all you'll get is the concept.
