An infobox
After much testing around with a regular table to imitate an infobox, it wasn't as sufficient to get tasks done.
First, many wikis such as wikipedia and wikia have this feature. It makes having to create a info table positioned to the right easy, efficient, and stylized when creating articles.
Second, if you were to create a regular table in substitution to an infobox, the table would need to be the first thing in the article otherwise the text outside of the table would spill to the right. As a consequence, the hover over a wiki link would not show anything, due to the table being in the way.
