"Wikipedia remains a lumpy work in progress. The entries can read as though they had been written by a seventh grader: clarity and concision are lacking; the facts may be sturdy, but the connective tissue is either anemic or absent; and citation is hit or miss. Wattenberg and Viégas, of I.B.M., note that the vast majority of Wikipedia edits consist of deletions and additions rather than of attempts to reorder paragraphs or to shape an entry as a whole, and they believe that Wikipedia’s twenty-five-line editing window deserves some of the blame. It is difficult to craft an article in its entirety when reading it piecemeal, and, given Wikipedians’ obsession with racking up edits, simple fixes often take priority over more complex edits. Wattenberg and Viégas have also identified a “first-mover advantage”: the initial contributor to an article often sets the tone, and that person is rarely a Macaulay or a Johnson. The over-all effect is jittery, the textual equivalent of a film shot with a handheld camera." - Know It All
