Italian Wikipedia recently started an experiment to enable anonymous editing for its editors. Many thanks to Florian and Nemo for making this happen!
They enabled it on the 1st November so now we have a month of data let me state about what we've found.
For the month of November anonymous edits counted for 50% of all edits on Italian Wikipedia and increased the average number of edits by roughly 55%.
Average edits before switch was 1688 Average edits after switch was 2619 Logged in editing took a slight dive as a result of this - 1687 edits were coming from logged in users before to 1305
The graph [1] shows not too much impact to the current trend for editing from logged in users but it's clear that anonymous editing does bring in slightly more edits, but not a radical amount to get us excited about.
Florian has recently written a patch that simplifies the workflow for editing such that clicking edit loads a screen with anon editing, sign in and sign up options. It will be interesting to see if this effects the data at all.
Can anyone from the Italian community analyse the types of anonymous edits that were made in the month of November and comment on what % of those got reverted / were bad edits?
I've included the data [1] (should be public) for anyone to analyse and pick apart.
