Subject: Re: [Wikitech-l] Anonymous editing impact on mobile
How can edits from logged-in users be down 152%? The maximum decrease
should be 100% - and that would mean no edits from logged-in users. Same
for first edits by logged-in users.
I seriously wonder about the number of "accounts" created on mobile - are
we really adding 0.05% of all of the current existing accounts every single
month just on mobile? Or does that include accounts that already existed
on a WMF site?

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]
