Hi all,
I have a very non-technical related question about the report card.
I am looking at this chart:
http://reportcard.wmflabs.org/graphs/unique_visitors
If I want to measure the unique visitors to Wikimedia projects should I sum up al the categories in this graph or just take the 'world' information?
I'm asking this because 'world' seems to suggest a summation of the other labels. However a sum of all regions does not equal the number under 'world'.
Cheers,
Maarten
