Reading some authors but not others is more difficult on a medium like a wiki, where the individual change is made by one author, but the resulting page may no longer gives a choice: The join authorship of a page no longer allows you to ignore twits. It's an all-or-nothing decision: Read the page or don't. In such a situation you might want to SplitThePage. (Sometimes you can skip over signed sections in ThreadMode, of course.)
