Anonymous editing was enabled on mobile web on 30th March 2015 to all users
(previous it was available in an experimental mode of the site). Now we
have almost a month's worth of data I thought it would be a good time to
check the impact... it's a little disappointing to be honest... but it
depends what we are optimising and consider the most important.
Quick summary:
* All edits up 154%
* Edits from logged in users down 152%
* Errors up 600%
* No noticeable impact on the new active editor graph [0] (editors that hit
5 edits in the month period)
* First edits by logged in users down 176% (although this could arguably be
said to be compensated by anonymous edits)
* New account creation up by 192%
Follow ups
* Aaron H, it would be great if you could report back with some findings on
the quality of the edits during this same period.
* Can anyone provide theories why registrations jumped so much? This might
be related to the change or because of something else
Details on the queries I ran:
In March for a 26 day period before the change:
* 170,948 total edits [1]
* 169,845 non-anonymous edits [6]
** by 40,658 distinct users [7]
* 26,617 users completely their first ever edit [11]
* 9,528 errors [8]
* 219,012 accounts created on mobile [12]
For a similar 26 day period in April
* 263,986 total edits [2]
* 136,079 non-anonymous edits [4]
** by 26,823 distinct users [5]
* 15,109 users completely their first ever edit [10]
* 58,394 errors [9]
* 419,976 accounts created on mobile [13]
