My Favorite Wikis lists your, ah, favorite wikis (positions deemed by your Editcount on each wiki). It lists them by their sitename.

When you make a wiki, it automatically appends "Wiki" to the end of the sitename, so that every English-language wiki created is in the format " Wiki". So if you take objection to "Wiki" appearing on your profile so many times, then you should direct your blame at the issue of sitenames, and I don't think there's a better alternative system.

As a side note, not all Wikia wikis follow the " Wiki" format. Take a look at User:DarkLantern. His favorite wikis are:
 * "The One Wiki to Rule Them All"
 * "The Babylon Project"
 * "Tardis"
 * "Little House on the Prairie Wiki"

Some wikis have customized SITENAMES that don't include the "Wiki" at the end, as he demonstrates. For reference, Special:Contact/wiki-name-change is the link to rename your wiki.
