In December 2005 during the John Seigenthaler biography controversy (http://en.wikipedia.org/wiki/John_Seigenthaler_Sr._Wikipedia_biography_contr...) it was decided to require that users create an account and log in before starting a new article. The ability of people to make changes without logging in remained unchanged.
Some people believed that Wikipedia's the high rate of growth may have outpaced its community's ability to monitor new articles, contributing to the Seigenthaler problem. It was hoped that the limitation of page creation would increase the quality of newly created pages, increase oversight over newly created pages, and avoid the creation of hoax articles. Since that point several attempts to study the impact of the change have been conducted. These studies have been unable to produce conclusive findings.
Around the time of the Seigenthaler controversy Wikipedia underwent a dramatic and discontinuous increase in traffic and editing activity beyond the high rate of growth Wikipedia had long been experiencing. It is very likely that the press surrounding this incident contributed to this increase. This increase had made it impossible to make conclusive statements about the impact limiting page creation.
Furthermore, if we ignore the growth effects the data suggests that the change has been harmful to the quality of Wikipedia. I must emphasize that all results have been inconclusive. We just can't tell.
Numerous discussions with Wikipedians, Foundation leaders, and Foundation staff going back for more than a year have generally been positive about the idea of re-enabling anonymous page creation.
In the time since late 2005 the English Wikipedia community has grown substantially. The nearly exponential growth rate in articles we previously experienced has stopped. Even if disabling anon page creation was beneficial then, there is no current evidence suggesting that the change continues to be beneficial. As such, barring complications, anonymous page creation will be re-enabled on English Wikipedia on Friday November 9th.
After a one month period, on December 9th, we will re-evaluate this decision using previously established methods (average article lifespan, rate of deletion, manual quality classification, random samplings of newly created articles, and most importantly, community discussion). If there is evidence of harm, anonymous page creation will be disabled to collect more data and provide time for discussion. If there is no significant evidence of harm, the issue will be evaluated again after six months. Further milestones and actions may be proposed at that time.
Finally the community will have the chance to make an informed decision on this subject. It would have been best if that had happened initially, but it wasn't possible then.
I hope that we can all look at this matter with optimism. If you are aware of a strong factually-grounded reason why this should not be done please provide it as soon as possible, either as a response to this list or emailed to me privately. If you have ideas on additional measurements we can perform after making this change or if you'd like to volunteer your effort for helping to perform a manual new article quality study next month, please let me know.
Interesting... Well, I do not know who exactly made that decision, but I am happy of it. I was never really convinced it was a good idea.
One thing I am very curious about is to know what the english speaking community will decide regarding the stable version system (display of flagged version, or display of current versions). I am personally VERY VERY much in favor of displaying the live version. But I have no idea if this has been discussed here and if so, what the general position was.
