Conclusions
[edit ]- The number of anonymous article contributors per month has fallen since 2007, but seems to have stabilized at a bit over 100,000 unique IPs editing in the main namespace per month. Compare this cohort to the 10-12% of English Wikipedia signups that stop mid-edit to create an account (full data)
- The number of revisions to articles by anonymous editors has been just below one million per month. This composes roughly 1/3 of the total revisions to English Wikipedia.
- Since 2006, the average revisions per session has hovered at just below two edits a session for anons. There has been much more movement in the average for registered accounts, in part due to bot activity, but it has generally been 5-6 edits per session. In terms of anonymous editor acquisition, this suggests that providing calls to register will not reach most anonymous editors if we wait for a string of multiple edits (more than two).
- The average time spent per editing session follows a similar pattern as average revisions per session. For anonymous editors, the average has been below 15 minutes per edit session. For registered accounts, including bots, the average is double, at just below 30 minutes.
Pre-registration anonymous activity
[edit ]Using the cu_changes table, we generated a dataset that contains a newcomers' pre-registration and first session activity. See the following diagram to get a sense of the kind of activity we're interested in:
In order to generate this, we gathered a sample of newly-registered users from the cu_changes table using this query:
SQL source code
|
|---|
SET@month_end=(SELECTmax(rc_timestamp)FROMrecentchanges); SET@month_start=DATE_FORMAT(@month_end-INTERVAL30DAY,"%Y%m%d%H%i%S"); SELECT user_idasid, user_nameasname, user_registrationasregistration, user_editcountaseditcount, cuc_ipasregistration_ip FROMuser INNERJOINcu_changesON cuc_user=user_idAND cuc_type=3AND cuc_actiontextLIKE"User account % was created" WHEREuser_registrationBETWEEN@month_startAND@month_end ANDuser_editcount>0 ANDuser_id%10=0 |
Using the registration_ip from this dataset, we scan the revision and archive looking for revisions with a user_text field that corresponds to the registration_ip. Using the edit session method with a 1 hour cutoff, we then gather the last session before registering (if any) and the first session since registering.
Results
[edit ]In my sample, 6.9% of newcomers who ended up making at least one edit in their first week edited as an IP before registering their account. I'm generating some histograms now to get a sense for how much they before and after registering.
So how do users who edit before registering behave compared to users who don't? The following plots include data from both the pre-registration session and the post-registration session.

What if we limit the analysis to just the post-registration session?

Conclusions
[edit ]- In our sample, 6.9% of newly-registered users edited anonymously within an hour before signing up.
- Users who edited anonymously right before signup are significantly more productive newcomers than the general population of editors
