RecentEdits is a back door into the April Fool’s gag at MeFi, which appears to be giving the wiki code a run for its’ money. However, a common trick appears to be the posting of spurious error messages in place of the collaborative content.
Adding to the confusion is the apparent rate of edits. Refreshing the page will almost certainly yeild a different result.
A useful link amidst the babel: Urgo.com is tracking the foolishness of the day.
